I'd like to design a customizable photo frame with two main parts: a bottom mat and a top mat, that join together. The photo will sit in a rabbet created by the top and bottom mat.

Here's a breakdown of the key features:

**Overall Structure:**

*   The frame should consist of two main parts: a bottom mat and a top mat.
*   The top mat should have a rabbet that overlaps the bottom mat, creating a recess for the photo.
*   The two mats are connected with cylindrical joints.

**Photo Dimensions:**

*   I need to be able to specify the `photoWidth`, `photoLength`, and `photoHeight` as parameters.
*   I'll also need a `photoSizeTolerance` parameter to add a little extra space for the photo, which should be applied to both the width and length dimensions.

**Border Dimensions:**

*   The border around the photo should be controlled by a `borderSize` parameter.
*   The border will have a `borderThickness`.
*   The corners of the frame should be rounded with a `borderRoundRadius` parameter.

**Joint Dimensions:**

*   The cylindrical joints that connect the top and bottom mats should have a `jointWidth` (diameter) and `jointLength` parameter.
* The holes on the bottom mat should have a specific `jointHoleTopThickness`, that is, the thickness on the top of the hole which is cut out of the bottom mat.
* I need the top mat to cut away part of the top of the cylinder to avoid it being too sharp. I will have a parameter `jointTopCutSize` which is the size of this cut.

**Other Parameters:**

*   I'd like to include optional anti-warping cylinders on both the top and bottom mats. These should have a `antiWarpingSize` (diameter) and `antiWarpingThickness`.
*   The `antiWarpingTotalNumber` parameter will let me select 4 or 8 of these cylinders around the edges of the frames.
*   I will have boolean `enableTopMatAntiWarping` and `enableBottomMatAntiWarping` parameters that turn these anti warping cylinders on and off on each mat.
*   The top mat should have a `TopMatRabbetDepth` parameter which specifies how deep the rabbet on the top mat should be.
*   I need a `shoulderSizeOfBottomMatRabbet` parameter which controls how much of the photo the bottom mat covers. This creates a lip where the photo will rest.

**Additional Considerations**

*   The script should be parametric, so I can easily adjust all of these dimensions.
*   I'd like a `debug` flag so I can preview different parts without having to generate everything each time.
*   The generated scad files should not depend on any specific libraries, such as MCAD or BOSL; I need pure OpenSCAD.
*   I want the joint connecting the top and bottom mat to be slightly scaled down on the top mat so that it fits in the joint hole of the bottom mat.

Can you create the necessary OpenSCAD file(s) for this photo frame?

Okay, I'm looking to create some custom arcade-style bezels and decks for a project, specifically designed to fit onto a "Hoodie" case. I need to generate these parts using OpenSCAD, and I’m hoping you can help me out with the code.

Essentially, I need to be able to design three different kinds of parts: a screen bezel (both front and back), and a control deck. All of these will need to have rounded corners that are specified as a hypotenuse - the length of a line drawn from the corner to the adjacent side if the object was a rectangle. The main goal is to be able to adjust dimensions, button layouts, etc., in a parametric way using OpenSCAD.

For the *screen bezel*, I'd like separate parts for the front and back. The front bezel should have parameters for the overall size, screen cutout size, and the rounded corners. It’s important to have some control over the thickness of the bezel itself, and the front should have an interior piece that slightly overlaps the exterior to add depth. The back bezel should be just a simple piece with a cutout for accessing the back of the screen. I need parameters to set the size of that rear access cutout, and its position relative to the corner.

The *control deck* part will be the most complex. It will need to handle different types of buttons and a joystick. I need to be able to specify the diameter and spacing of large buttons arranged in a grid, as well as the diameter and spacing of smaller buttons in a row. For the joystick, I need to define the overall diameter of the joystick, and then specify the mounting holes underneath. There should be parameters for the number of mounting holes, their spacing, and whether that mounting pattern is rectangular or square (for now, assume it's always a vertical pair with a fixed spacing). It should also have interior and exterior dimensions, like the screen bezel.

The critical thing is that all of these parts have those rounded corners based on a hypotenuse dimension, not a radius. I also need to be able to set the thickness of each part independently. So, each part will need to be a rounded rectangle of a specified height and specific measurements for the rounding.

I am expecting the output as one or more .scad files, but I’m really only concerned with the main parts for now. I don't need any complex support structures, mounting hardware or anything like that. Can you provide the code needed to generate these parts?

It would be great if the code was well-commented, to help me understand how it works. I would also appreciate the use of named modules instead of unnamed code blocks wherever possible. I'm not using any libraries currently.

Hi! I'm looking for a parametric OpenSCAD design for a center finder tool. I want to be able to customize it for different material thicknesses and also control the spacing of the marking notches.

Here’s what I'm envisioning:

**Core Functionality:**

*   The tool will be a square, designed to sit on the edges of a board and allow you to scribe lines to find the center.
*   It needs to have two main material thickness parameters: `woodWidth` for the thickness that runs perpendicular to one set of scribe lines, and `woodWidth2` for the thickness that runs perpendicular to the other set of scribe lines. These values will be in *inches*.
*   There should be adjustable marking notches along the edges of the square that create the scribe lines. I need to be able to control the spacing between the notches, `notchSpacing`, in *inches* as well. There needs to be an ability to select how many are drawn out, or the length they are drawn out for.
*   I'll need to adjust the tolerance, `tolorance`, in *mm*.
*   There needs to be adjustable sidewall thickness for the square itself, `sidewallThickness` in *mm*.

**Specific Features:**

*   The overall size of the tool should be 100mm x 100mm.
*   There needs to be an option to have the central intersection of the two wood widths removed to better allow the user to see where the lines intersect. This is achieved by setting `woodWidth2` to a negative number, -2x the wall thickness.
*   The marking lines will need to be a `scribeWidth` wide, in *mm*, on each axis
*   The material thicknesses parameters will take the material thickness given in inches and add in the specified tolerance, converting it to mm.
*   The actual mark will need to extend out a bit so that you can see it when making your mark. The depth of the mark will be set at 2.5mm, and the depth it will extend out from the surface will be 1.5mm
*   The length of the scribe line for the marking notches will be 8mm
*   The marking lines needs to be centered on each axis.

**Parametrization:**

I would like the following parameters:

*   `woodWidth` (inches): Material thickness for one axis of the finder.
*   `woodWidth2` (inches): Material thickness for the other axis. Can be negative to remove the center intersection.
*   `tolorance` (mm): Tolerance for material thickness.
*   `sidewallThickness` (mm): The thickness of the square's walls.
*   `notchSpacing` (inches): Spacing between the marking notches.
*  `scribeWidth` (mm): The width of the marking scribe.
*  `numOfMarkings`: The number of markings to draw on each side of the center.

**Structure:**

I'm imagining a modular design, with distinct modules for:

*   The main square body (`corner`)
*   The markings along the edges (`markings`)
*   A wood block that rests on the boards (`wood`).
*   A corner cutter that will be used to remove the intersection (`cornerCutter`).

I don't have any code written already, so you'll have to generate everything from scratch. I'm okay with the design using standard OpenSCAD libraries, but if you use one, make sure to let me know.

Let me know if you have any questions!

Hi, I'm looking to create a customizable number plate keyring and I'd like to use OpenSCAD to make it parametric. I need the following features:

*   **Text:** The ability to customize the text on the plate. I'd like a setting to control if the text should be inset or not, and also control the thickness of the text itself. I'd like to use the "Mandatory" font from K-Type, so it needs to include that font in the file. I'm assuming it is okay to add fonts to the same folder as the .scad files?

*   **Plate:** I need to be able to adjust the overall plate width, the border width around the plate, the overall plate thickness, and add some additional material thickness to the border specifically.

*   **Keyring Hole:** I'd like an option to include a keyring hole, along with settings to control the hole diameter and the thickness of the material surrounding it.

*   **Priming Block:** I'd like a feature for adding a priming block for multi-filament printing. It should have settings for the diameter (as a percentage), and x and y offsets, also as percentages.

I also need to be able to print this in two colors. The first color should be for the plate and the text. The second should be for the border and the keyring hole if those features are selected.

Could you please generate the necessary OpenSCAD file(s) for this? I'm aware of the licensing requirements for the Mandatory font, and I will ensure it is used as intended.

I'm looking to create a customizable round cap with a latching mechanism, and I need your help designing it in OpenSCAD. I want the design to be parametric so I can easily adjust various dimensions.

Here's what I have in mind:

The cap should have a rounded top, and the main body of the cap will be cylindrical. There's going to be a latch mechanism on opposite sides of the cap. Each latch will be a short, rectangular protrusion. I need to control the following parameters:

*   **Latch Width (W_LATCH):** The width of each latch.
*   **Latch Height (H_LATCH):** The height of each latch.
*   **Latch Offset (O_LATCH):** How far down the latch extends from the bottom of the cap.
*   **Latch Outer Thickness (OT_LATCH):** The outer thickness of the latch.
*   **Latch Inner Thickness (IT_LATCH):** The inner thickness of the latch where it connects to the cap body.
*   **Cap Diameter (D_CAP):** The diameter of the main cylindrical portion of the cap.
*   **Cap Height (H_CAP):** The height of the main cylindrical portion of the cap (not including the rounded top or latches).
*   **Cap Radius (R_CAP):** The radius used to create the rounded top of the cap. This needs to be able to control the curvature.
*   **Print Mode (M_PRINT):** I need to be able to specify a print orientation so I can choose between things like "top down", "bottom up", "side", or "side angled," based on my printer and needs. Let's use values 0-4 for this.
    *   0: Top down (top surface)
    *   1: Bottom up (bottom surface)
    *   2: Side (max strength)
    *   3: Side angled (strength > surface)
    *   4: Top angled (surface > strength)

I'd also want the design to check that `R_CAP` is large enough given the other dimensions so the rounded top can complete correctly.

I don't want to use any particular libraries for this, just standard OpenSCAD functions.  Can you generate the necessary OpenSCAD code?

Okay, I need some help designing a shelf bracket for 3D printing. I've been messing around with OpenSCAD, and I think I have the basic idea, but I'm struggling to get all the parameters right. I would like to use modules to help make it cleaner and easier to modify. I've seen some good work done with the BOSL2 library. So, I'd like to leverage that.

Basically, the bracket is a standard right angle. It has a horizontal "base" leg and a vertical "side" leg, connected by a diagonal brace. Each leg should have two screw holes for mounting, and the diagonal brace needs a cutout to allow access for a screwdriver, as demonstrated in some prior designs I've seen on the DrVAX channel.

Here are the key parameters I'm envisioning:

*   **`base`**: Length of the horizontal leg.
*   **`side`**: Length of the vertical leg.
*   **`width`**: Width of both legs and the diagonal brace.
*   **`thickness`**: Thickness of the legs and the diagonal brace.
*   **`screw_hole_diameter`**: Diameter of the screw holes.
*   **`screw_hole_offset_percent`**: A percentage value that defines the position of the screw holes on each leg. This should be a percentage, not a fixed distance.
*   **`screwdriver_slot_width`**: The diameter of the cylindrical cutout for the screw driver in the angled brace, with the slot width scaling by some factor of the diameter.
*   **`screwdriver_slot_depth`**: The depth of the slot.

I'd like the screw holes on each leg to be placed symmetrically. So, if `screw_hole_offset_percent` is 20%, the first hole would be 20% of the way along the leg and the second would be 80% of the way along the leg.

Can you generate an OpenSCAD file, or several files if that makes more sense, that uses these parameters and includes appropriate modules? I think modules for the legs, screw holes, diagonal support and the slot would be great.  I am looking for a clean, well-organized parametric design that I can customize easily. It would be great if it also has some colors assigned to the different parts. Also, can you verify that the `screwdriver_slot` is at an appropriate angle to the diagonal brace and not simply rotated, similar to the examples I provided?

Hey, I need some help designing a pocket hole jig for woodworking. I've got some design requirements, and I'm thinking we can make it parametric so I can adjust it later on.

Basically, I want to design an insert with two angled drill guide holes. I've already got a basic SCAD file for that, which I can give you, but I'd like to make this more comprehensive. The existing file has parameters for:

*   Hole diameter (`d`)
*   Length (`l`)
*   Width (`w`)
*   Height (`h`)
*   Angle (`a`)

I'd like the design to use those same parameters. Here's the existing SCAD code:

```scad
// Hole diameter
d=8;
// Length
l=66.8;
// Width
w=38.2;
// Heigth
h=18.6;
// Angle
a=17;

/* [Hidden] */
$fn=100;

difference() {
    cube([l,w,h]);
    translate([l,0,0]) rotate([0,-a,0]) cube([h*tan(a),w,h+h*tan(a)*tan(a)]);
    // holes
    translate([l,0,0]) rotate([0,270-a,0]) translate([11,9,0]) cylinder(h=100,d=d);
    translate([l,0,0]) rotate([0,270-a,0]) translate([11,w-9,0]) cylinder(h=100,d=d);
}
```

Beyond that, the jig will need a base to which the insert will attach. The existing design shows this as an L-shaped piece that the insert sits on top of. I want to make that parametric as well. The base should have mounting holes to allow for the insert to be attached using M6 bolts. I would like the hole locations to also be parametric.

The whole thing is designed to use M6 hardware.  I'd like parameters for:

*   Bolt hole spacing on the insert (`bolt_spacing_x`, `bolt_spacing_y`)
*   Bolt hole diameters (`bolt_hole_diameter`)
*   Bolt head recess diameter and depth
    (`bolt_recess_diameter`, `bolt_recess_depth`)
*   The thickness of the base (`base_thickness`)
*   Length, width, and height of the base
    (`base_length`, `base_width`, `base_height`)
*   Offset from insert to base (`insert_offset`)

I am planning on using this jig with a similar jig I bought, so the base should be designed so that I can insert an M6 coupling nut into a hex recess and fix the M6 bolt with a nylon lock nut and washer on the other side.  Could you add parameters for the coupling nut dimensions and the hex recess dimensions?

*   Coupling nut length (`coupling_nut_length`)
*   Coupling nut outer diameter (`coupling_nut_diameter`)
*   Hex recess size and depth (`hex_recess_size`, `hex_recess_depth`)
*   Washer diameter (`washer_diameter`)
*   Washer thickness (`washer_thickness`)

Finally, I want to be able to adjust some clearances. I'd like a parameter for overall tolerance (`tolerance`), and separate parameters for the tolerance around the mounting holes (`bolt_hole_tolerance`) and the tolerance around the guide holes (`guide_hole_tolerance`).

I think that's everything. I'd like this organized into separate modules for easier modification and reuse. I'm not too picky about the structure - whatever you think makes the most sense is fine with me.

Drill_guide_insert.scad:
```

// Hole diameter
d=8;
// Length
l=66.8;
// Width
w=38.2;
// Heigth
h=18.6;
// Angle
a=17;

/* [Hidden] */
$fn=100;

difference() {
    cube([l,w,h]);
    translate([l,0,0]) rotate([0,-a,0]) cube([h*tan(a),w,h+h*tan(a)*tan(a)]);
    // holes
    translate([l,0,0]) rotate([0,270-a,0]) translate([11,9,0]) cylinder(h=100,d=d);
    translate([l,0,0]) rotate([0,270-a,0]) translate([11,w-9,0]) cylinder(h=100,d=d);

I'm looking for an OpenSCAD design for a customizable cable clip that attaches to poles or pipes. I've seen one that looks pretty good, but it would be nice if I could specify all the parameters.

Here are the key features and parameters I need:

**General:**

*   The clip should consist of a ring that clamps around the pole and a clip section to hold the cables.
*   I need to control the material thickness and height.

**Pole/Ring Parameters:**

*   `Pole_Diameter`: The diameter of the pole or pipe the clip will attach to.
*   `Pole_Gap_Angle`: The angle of the gap in the ring, this will allow it to flex around the pole.

**Clip Parameters:**

*   `Clip_Gap_Width`:  The width of the gap in the clip, representing the maximum cable diameter.
*   `Clip_Length_Angle`: The length of the clip as an angle.
*  `Clip_Direction`:  The direction of the clip opening.  It should be able to open to the left, right, or have a clip on both sides. Let's represent this with `1` for left, `0` for right and `2` for both.
*   `Clip_Lip_Gap_Percent`: The percentage of the clip gap that the lip occupies.  This will affect the shape of the clip opening and should be a percentage value.

**Material Parameters**

* `Material_Thickness`: The thickness of the material used for the clip
* `Material_Height`: The height of the material used for the clip

I'd like the final OpenSCAD design to include all these parameters and be customizable via the OpenSCAD customizer. Could you generate a design for this? I don't need any special libraries, just the standard OpenSCAD functionality.

Also, I'm planning on 3D printing this, so it would be nice to keep the design relatively simple and printable without supports.

I need an OpenSCAD design for a finger splint, something that will protect my fingertip. It needs to be parametric so I can adjust it for different finger sizes.  I'm looking for a design that's essentially a short, hollow cylinder, wider at the top than the bottom, with a rounded end on top like a semi-sphere. I also want holes in it for ventilation and some internal ribs near the bottom for grip. I saw a similar design but want to build my own from scratch and add some extra features.

Specifically, I'd like the following parameters to be adjustable:

*   `height`: The overall height of the cylindrical portion of the splint (excluding the semi-sphere), in mm.
*   `top_inner_diameter`: The inner diameter of the opening at the top of the cylinder, in mm.
*   `top_outer_diameter`: The outer diameter of the top, in mm.
*   `bottom_inner_diameter`: The inner diameter of the opening at the bottom of the cylinder, in mm.
*  `bottom_outer_diameter`:  The outer diameter of the bottom, in mm.
*   `hole_radius`: The radius of the ventilation holes, in mm.
*   `hole_rows`: Number of rows of holes down the splint
*   `hole_columns`: Number of columns of holes around the splint.
* `rib_height`: The height of each internal rib, in mm.
* `rib_thickness`: The thickness of each internal rib, in mm.
* `num_ribs`: The number of internal ribs near the bottom.

The design should:

1.  Start with a hollow cylinder that transitions from the bottom diameter to the top diameter.
2.  Add a semi-sphere to the top to create a rounded end.
3.  Subtract a smaller cylinder inside to make it hollow. The internal diameter should be uniform, not conical. This cylinder should be slightly shorter to match the radius of the semi-sphere (e.g. if the outer cylinder is 40mm tall and the top outer diameter is 24mm then the inner cylinder is 38mm tall) to avoid any interior clipping issues.
4.  Add a few internal ribs near the bottom to improve grip. These should be cylindrical, subtracted from the main body to be rings that stick inwards.
5.  Include a slit or opening down one side of the splint. It should go from the top all the way down.
6.  Add a grid of ventilation holes around the body of the splint. The holes should be arranged in a somewhat evenly spaced grid, determined by the `hole_rows` and `hole_columns`.
7.  Include two rings of smaller holes around the semi-sphere at the top. These should also be controlled parametrically (hole radius, number of holes, radius at which they are placed)

I'm not looking for a super complex design but something functional and easy to customize. I would prefer not to use any libraries, such as MCAD, BOSL, etc., but if a library would dramatically simplify the design I'm open to it.  Thanks!

Okay, I'd like to design a seedling tray, but I need it to be parametric so I can easily adjust the size and number of cells. I'm picturing a rectangular tray with a grid of square or rectangular cells, plus a separate, removable grid that fits inside each cell to act as a bottom.

Here's a breakdown of what I need:

**Tray Structure:**

*   **Overall dimensions:** The tray should be a rectangular box with customizable width, height, and depth.
*   **Number of cells:** I want to be able to specify the number of cells in both the width (columns) and height (rows) directions.
*   **Wall thickness:**  The outer walls and the walls between the cells need a thickness parameter. This should be a multiple of the line width for 3D printing, probably best to have it adjustable.
*   **Bottom thickness:** The main tray bottom thickness should be configurable, for example, 1mm.

**Removable Grate (Bottoms):**

*   **Individual grates:** I want each cell to have its own removable grate that fits inside.
*   **Grate thickness:** The thickness of the grates needs to be adjustable as well.
*   **Grate grid:** Each grate needs a grid pattern of holes for drainage.  I'd like to specify how many cells in the grid of the grate as well as the wall thickness for that grate grid.
*   **Support:** There needs to be small supports that hold the grates up a bit off of the bottom of the tray, so that I can push the grate up to eject the plant. The size of that support needs to be configurable too.

**Important Parameters:**

*   `width`: Total width of the tray.
*   `height`: Total height of the tray.
*   `depth`: Depth of the cells.
*   `n_columns`: Number of cells across the width.
*   `n_rows`: Number of cells across the height.
*   `wall`: Thickness of the walls (outer and cell dividers).
*   `bottom`: Thickness of the tray's bottom.
*   `support_size`: Size of the supports under the grates, this should be the space between the bottom of the tray and the grate.
*   `grate_thickness`: Thickness of the grates.
*   `grate_n_cells`: Number of holes in the grate (both x and y dimension, i.e. for a 3x3 grate set this to 3).
*    `grate_wall`: Thickness of walls in the grate.

**Workflow/Output**

*   I want to be able to generate the main tray itself *and* the grates separately, so I can print the tray first and then the grates.  Maybe a variable or boolean `print_cups` that determines whether to generate the main tray or the grates would do the trick? if true, generate the tray, if false, generate the grates.

Could you create an OpenSCAD file (or set of files, if that's more convenient) that accomplishes this? I'm not using any libraries currently, but if it simplifies things, I'm open to using external libraries too.

I'm looking to create a parametric fan case that can be used as a solder fume extractor. I need the case to be customizable for different fan sizes, filter thicknesses, and include a grill cover for both the intake and exhaust sides of the fan.

Here's what I have in mind:

*   **Fan Dimensions:** The design should be parameterized for `fan_width`, `fan_height`, and `fan_depth`.
*   **Case Thickness:** I need a parameter for the thickness of the case walls, `case_thickness`.
*   **Filter Thickness:**  The carbon filter will sit on one side, so there should be a parameter `filter_thickness` to set how deep the filter section should be.
*   **Grill Design:**  The grill should be a bullseye/concentric ring pattern. The number of rings should be a parameter `ring_count`. It should include a cross support for stability.
*   **Easter Egg:** It'd be nice to have an optional `easter_egg` parameter to add a symbol or text to the grill, maybe something like a smiley face (U+263A). This should use the "Arial" font and be centered.
*   **Mounting:** I'd like to be able to add a simple mounting plate so I can attach the whole thing to a frame. Perhaps just a simple rectangle extending from the side of the case.

I'm thinking I will need separate modules for the case, fan grate, and an optional mounting plate. I'd like to be able to easily adjust all these parameters.

I'm familiar with OpenSCAD, so I don't need a lot of hand-holding. However, I'd prefer that the design avoid external dependencies if possible. That is, no need to use MCAD, BOSL, etc.

Hey there! I'm looking to get some customizable drawer boxes designed in OpenSCAD. I found this awesome design by 1SPIRE that I'd love to build on, and I need your help.

Essentially, I want to create a system where I can have a main drawer with a grid pattern on the bottom, and then individual boxes that fit into that grid. I want to be able to adjust a bunch of parameters to customize the dimensions, grid spacing, and box sizes. I've already messed around with some settings on another design but it's a bit limited. I'll go through the specific parameters I need.

Here's a breakdown of what I need to control:

**Overall Drawer Parameters**
*   `ID_W`: Inside Width of the main drawer
*   `ID_L`: Inside Length of the main drawer
*   `ID_H`: Inside Height of the main drawer

**Grid & Matrix Parameters**
*   `MAT_W`: Number of grid "units" or columns across the width of the main drawer.
*   `MAT_L`: Number of grid "units" or rows along the length of the main drawer.
*    `MAT_H`: Number of "height units" for the boxes within the drawer. I want the boxes to be able to be variable in height along some matrix that this value represents.
*   `Tol`: Tolerance or space between the grid units and the boxes.
*   `G_rad`: The radius of the grid indentations on the bottom of the drawer and on the boxes.

**Individual Box Parameters**
*   `B_WT`: The wall thickness of the individual boxes.
*   `B_BT`: The bottom thickness of the individual boxes. This is important because I want the inside of the box bottom to be flat, while the outside bottom will have those grid cutouts. If I set it to more than `G_rad`, it'll work.
*   `B_rad`:  The radius of the corners inside the individual boxes.
*   `ST`: A boolean flag (0 or 1) to add a sticker lip to the box.
*   `ST_W`: The width of the sticker lip.
*    `ST_H`: The height of the sticker lip.
*   `$fn`:  The number of fragments to use for circles.

**Parameters for the Grid and Boxes being Printed**
*   `GTP_W`:  Number of grid sections to print along the width. Must be less than `MAT_W`. This lets me print just a piece of the grid, if I want to.
*   `GTP_L`: Number of grid sections to print along the length. Must be less than `MAT_L`. Same idea, lets me print less if needed.
*   `GI`: A boolean flag (0 or 1) to indicate whether or not the individual boxes will have a grid inlay.
*    `BTP_W`: The number of matrix units that the box occupies along the width. Must be less than `MAT_W`.
*    `BTP_L`: The number of matrix units that the box occupies along the length. Must be less than `MAT_L`.
*    `BTP_H`: The number of matrix units that the box occupies along the height. Must be less than `MAT_H`.

**Box Separators Parameters**
*   `DST`: A flag (0 or 1) to choose if sticker lips are duplicated by the box separators.
*   `BTP_SW`:  The number of separators along the width of the box. Must be less than `BTP_W`.
*   `BTP_SL`:  The number of separators along the length of the box. Must be less than `BTP_L`.

**Preview and Render**
*   `Preview`: An integer to control what part of the design is rendered
    *   0: Drawer and grid preview
    *   1: Grid to print
    *   2: Setup Preview (Shows a matrix of boxes within the drawer)
    *   3: Box to print

I'm thinking I'll need at least a few modules or functions to handle the drawer, the grid itself, the grid units, and the individual boxes, and I want a top level module to decide what should render. It would be great to have some comments in the code too!

Could you generate that for me? I don't need any specific libraries, just the core OpenSCAD functionality.

Okay, I'd like to create a parametric design for a vase based on Rhodonea curves, also known as rose curves. I've seen some examples online, and they are very visually interesting! I want to be able to customize several aspects, and I want to be able to choose to create a bowl instead of a vase.

The core of the design should be a 2D Rhodonea curve that's then extruded into 3D. The curve itself is defined by two parameters, 'n' and 'd' as shown in the Wikipedia page for Rose (mathematics) that I'll paste below.

https://en.wikipedia.org/wiki/Rose_(mathematics)

I want to be able to control:

*   **petals (n):** This is the 'n' parameter from the Rose equation. It will control the number of petals (or lobes) in the curve. It should accept positive integers.
*   **amplitude (d):** This is the 'd' parameter from the Rose equation. I'm not exactly sure what it controls visually yet, but it should also accept positive integers.
*   **radius:** This will define the overall size of the base curve. This will have to be a non-negative number, and probably a positive number in practice.
*  **height:** The height of the extruded vase. If it is zero, then no vase will be extruded and only the 2D curve will be generated.
*   **wall_thickness:** The thickness of the extruded curve. This should be a positive number.
*   **base_thickness:** How thick the base of the vase should be.  If this is zero, there should be no base.
*   **extrude_scale:** A scaling factor for the extrusion, so the top can be larger or smaller than the base.
*   **extrude_twist:** An optional twist to the extrusion, in degrees.

I'd like for the final shape to be a vase or bowl (if the height is 0, just make the bowl or base shape). And, if a base is specified, a cylinder should be used to form the bottom part.

I am not sure what the best approach will be. My initial thinking was to construct the 2D curve from a series of joined dots. Each dot is determined by rotating a translation by some angle. After this, create a hull. This would then be extruded.

Also, it would be nice to have $fn to control the resolution of the circles in each dot. It would also control how many "dots" are used to draw each petal.

Could you provide the OpenSCAD code for this? I'm looking for a fully parametric solution, that includes all of these inputs and can choose between a bowl and a vase. I think it's important that the extrusion have a twist, so that the vase is more interesting.

Okay, I need a parametric OpenSCAD design for a socket organizer, specifically for metric sockets used in automotive work. I'm not looking for something universal with pegs for every size under the sun, but something I can customize for the specific sockets I use regularly.

Here's the breakdown of what I'm looking for:

1.  **Individual Socket Holders:** The design should create individual "pockets" or cylindrical depressions for each socket to sit in. Each pocket needs to be sized appropriately to hold a socket with a snug fit (friction fit).

2.  **Parametric Socket Diameters:** I need to be able to specify the inner diameter for *each* socket holder in a list. It needs to be easily changeable so I can adjust if needed.

3.  **Parametric Socket Labels:** Similarly, I need a corresponding list of labels to be displayed with each socket holder, probably on the side. These would be the socket sizes, e.g. "10", "13", "17".

4.  **Linked Arrangement:** All of these individual socket holders should be linked together in a single row, like a single piece, making sure they all line up nicely. The horizontal spacing between sockets can be calculated based on their diameters. The code should be able to handle different sizes in the same row.

5.  **Wall Thickness:** I'd like a parameter for wall thickness between the sockets.  It should also be used for the outer wall of the holder.

6. **Label Style**: I want two options for the label: either printed onto the side of the holder *or* recessed into the bottom of the socket holder. This should be an easy toggle with a parameter, maybe a `label_inside` parameter which would be `0` for label on the side and `1` for label inside the bottom. The label itself should also be parametric with font size and thickness being able to be changed.

7. **Bottom Height**: I want a parameter for the overall height of the bottom part of the holder and a parameter for the height of the inner cylinder for the socket. This will allow some customizability in how far the socket sits inside the holder.

8. **Adapter arm**: Some of the sockets have an additional adapter arm that's attached to the side which will hold them in. This should be an additional parameter that's optional, and the dimensions of the arm can be parameterized.

9.  **Easy Customization**: The primary goal is to make this easy to modify for different socket sets. It needs to handle a list of socket sizes and labels, handle different sizes in the same row, and have basic dimensional parameters for things like wall thickness and spacing.

I think that's about everything. I'm hoping this can be done without needing any external libraries, just using vanilla OpenSCAD.

Hey, I'd like to design a set of customizable, interlocking coasters that form a triangle shape. I have a basic idea, but I need a fully parametric design that's easy to modify.

Here's what I envision:

*   **Basic Shape:** The overall arrangement of coasters should form an equilateral triangle. Each coaster should be a cylinder.
*   **Interlocking:** The coasters should fit together snugly.
*   **Number of Rows:** I want to be able to specify how many rows of coasters are on each side of the triangle, allowing for different sizes.
*   **Inner Diameter:** I need to control the diameter of the inside circle of each coaster where the cup will sit.
*   **Wall and Floor Thickness:** I need to be able to set the thickness of the material surrounding the inner diameter and also the base of the coaster itself.
*  **Lip Height:** I also want a lip around the top of the coaster to keep condensation from running off the edge, so I'd like a parameter for that.
*   **Parametric:** I'd like the design to be fully parametric, so I can adjust all of these values using variables at the beginning of the file.
*   **OpenSCAD:** I need the code to be in OpenSCAD format.

I'm pretty new to OpenSCAD, so a clear and well-commented file would be great. No special libraries needed for this, just the standard OpenSCAD functions. Can you generate the SCAD code for me?
