I'd like to design a stackable CD stand, and I'm hoping you can help me generate the necessary OpenSCAD files. It will consist of two main parts: a base/foot and stackable CD holders.

The foot will have a main stackable part (cylinder with a top hole) and then have feet that extend out from the base. I want to be able to control the number of feet, their width and length, and their distance from the center. Each foot should also have a cylindrical end. I’d like to also be able to control the base height, width, top height, and top width of the stackable part of the foot. I'm also using a top cone on the stackable parts to aid in stacking, and I would like control over the cone height. Additionally, I want a tolerance setting for the hole that is cut in the base.

The CD holders will be stackable as well. They should have the same stackable shape as the foot (cylinder with the top hole/cone) so they will stack on the foot and each other. In the center of the top of the CD holder I want a cylindrical pole with a small hat for holding the CD, and a base below the pole. I'd like to control all these dimensions, such as pole radius, pole height, hat height, and base width, and height.

There's also a shaft that will connect the holder to the pole that i need to be able to control the length and width of. The shaft also needs to be at a 45 degree angle.

I need to be able to control the resolution for all these parts as well.

So to reiterate: I'm looking for two modules that can be used in OpenSCAD; one for the foot and another for the stackable CD holder, with all of the described parameters as variables. If possible, could you use descriptive variable names? I'm looking for all new code from scratch rather than modification. I don't think I need any external libraries.

Hey, so I've got this existing OpenSCAD design, "WireHolderHacked.scad", for a cable holder, and I need to expand it into something a bit more flexible. I want to be able to create a rack or array of these holders, not just the triple holder I have now. The original design is pretty customizable with variables for cable diameter, table thickness, tab lengths, grip sizes, thumbwheel height, and some more advanced parameters. I'd like to maintain all of those customization options and make it so that I can control the number of rows and columns in the rack, as well as the spacing between each holder.

The core design uses a few key components: an inner barrel that holds the cable, an outer holder, tabs for mounting to a table, and little thumbwheels on either end. It also uses a triangle grip on the tabs, and allows the user to specify how thick the "neck" and the holder overall is, along with tolerances for various parts. I want to be able to control all of this for the array. The "show_seperate" option that splits the model into separate parts for printing should be retained, too.

I'm thinking I'll need a new module or function that will handle generating a single holder (maybe using the existing logic in `baseUnit` or some variation of it). Then another module would take that and repeat it in a grid pattern based on user-specified row and column counts and the spacing between the holders.

I think the parameters should allow me to control:

*   **Global parameters:**
    *   `show_seperate` (yes/no): to split the holder for better printing of tight tolerances.
*   **Basic parameters** (just like in the old file):
    *   `cable_diameter`: Diameter of the cable in mm.
    *   `table_thickness`: Distance between the tabs in mm
    *   `tolerance`: Spacing between moving parts of the holder in mm
*   **Table Tab Parameters:**
    *   `tab_length`: Length of table tabs in mm.
    *   `tab_thickness`: Thickness of table tabs in mm.
*   **Table Grip Parameters:**
    *   `grip_height`: Height of triangular grip in mm.
    *   `grip_width`: Width of triangular grip in mm.
*   **Thumbwheel Parameters:**
    *   `thumbwheel_height`: Height of thumbwheels in mm.
*   **Advanced Parameters:**
    *   `retainer_factor`: Factor for barrel lift (play around with this - 3 to 10)
    *   `plane_cut_factor`: Cut depth factor (values 0 to 2)
*   **Advanced Neck Parameters:**
    *   `neck_thickness`: Thickness of the inner rotating cuff in mm.
*   **Advanced Holder Parameters:**
    *   `holder_thickness`: Overall thickness of the outer holder in mm.
*   **Array Parameters**
    *   `rows`: Number of rows of holders
    *   `cols`: Number of columns of holders
    *   `spacing_x`: horizontal spacing between holders
    *   `spacing_y`: vertical spacing between holders

I'd like to keep using `$fn` for the cylinder quality. Also, I'm not using any external libraries at the moment, so let's just stick with basic OpenSCAD functionality. Can you help me generate this? I'd prefer if it's split into a couple of files if that helps with organization.

Hey, I'm working on a project to create a fully parametric, 3D-printable chisel that can be made on an open-source metal RepRap printer. I've got a basic design in mind, but I need help making it more flexible and robust in OpenSCAD.

My current chisel design has a rectangular handle and a wedge-shaped blade. I need the following parameters:

*   **Handle Length (L):** The overall length of the handle.
*   **Handle Width (w):** The width of the handle.
*   **Handle Height (h):** The height of the handle.
*   **Blade Length (t):** The length of the blade portion.
*   **Blade Width (b):** The width of the blade at its widest point.
*   **Minimum Layer Height (a):** Used to control the height of the "blade" at its thinnest point.

I'd like to be able to adjust these parameters to make various sizes of chisels.

Here's what I have in mind:

1.  The handle should be a simple rectangular prism.
2.  The blade should start at one end of the handle and taper down to a minimum height "a". It should be connected to the handle using a hull.
3.  I would really like for the blade to connect to the handle using the *hull* function - it gives a good aesthetic.

Could you generate an OpenSCAD file(s) for me that does all of this? Please make sure to use comments to explain what's going on, and provide ways to quickly change variables for various sizes. I don't need any libraries this time, I just want it all in base OpenSCAD. Thanks so much!

Hi, I'm working on a project to create open-source tools for sustainable development, and I need a parametric design for a series of chisels that can be 3D-printed, ideally in metal.

I'm looking for an OpenSCAD design that is highly customizable. I'm picturing a basic chisel shape consisting of a handle and a tapered, angled tip, with a rectangular cross-section for the handle. I want to be able to control the length of the handle, the length of the tip, the width and height of the handle, and also the angle of the tip. I also need the ability to control the minimum printing step height, as this will affect the finish of the print.

I want the design to be parametric so I can easily change these dimensions to create a variety of sizes. Can you generate an OpenSCAD file that allows for this?

Also, a nice touch would be if the tip could have an option to add a flat edge on the end. It doesn't need to be a complex option, just a boolean to enable/disable. If it's enabled I'd like to control the flat edge length.

For libraries, I'm happy with whatever libraries make this easiest. But since we're printing in metal, I'd prefer if you could stick to MCAD or BOSL2 for parametric designs if possible. I don't necessarily need the threads or other features from MCAD, I just like it for parametric stuff.

I need a custom battery cover generator, and I've seen a couple of attempts at this online but they have flaws. I want to design a parametric OpenSCAD module that is flexible and lets me control all the dimensions.

Here are the features I need:

*   **Basic Shape:** The cover should have a rectangular base with rounded corners. I need to be able to control the length, width, and thickness of the cover, as well as the corner radius. There should also be a `case_thickness` variable to specify how thick the plastic of the device is that the cover attaches to.
*   **Ears:** The cover needs ear tabs that attach to the main device with screws.  I need to control the width, length, and spacing of these tabs. I also need to control the thickness of the case where the ears attach (`ear_case_thickness`).
*   **Clip:** There should be a clip on the opposite side from the ears for securing the cover. I need to control the overall width of the clip, the width of the clip's engagement portion (`clip_width_sides`), the length of the clip itself (`clip_length`), and how far it protrudes from the battery case (`clip_depth`, also used as the z-depth of a trimming cut). I need a `clip_length_catch` parameter to account for front-engaging clips in addition to side-engaging clips (if unused it will be 0), and a `clip_case_thickness` parameter for controlling how far the clip engages. Additionally, there needs to be a finger tab with adjustable thickness (`tab_thickness`).
*   **Gussets:** I'd like to be able to optionally add support gussets to the design. These should be configurable in terms of their orientation (along the length or width of the clip), thickness, height, and spacing. If gusset thickness is set to 0 then they should not be generated.
*   **Resolution:** There needs to be a `$fn` parameter to control the resolution of the curves.
*   **Support Material:** I need a variable to specify how thick the cover support material will be. It will be subtracted from the ear tabs to ensure the cover fits well.

I'd like this as a single SCAD file that contains the main `cover` module and any submodules required. It doesn't need to use any external libraries.

Hey! I'm looking to create a customizable version of these heart gears I found. I really like the design from heartgears2.scad, which uses the MCAD library, specifically `involute_gears.scad`. I want to be able to tweak a few things, but mostly I'd like the heart shape to be parametric, and I'd like to be able to easily change the pin connector design. Also, instead of just having 3 gear ratios, I'd like to be able to define gear ratios more precisely or specify them as input parameters. Ideally, I'd like to be able to specify the number of turns per cycle, rather than having it be fixed to the chosen gear ratio.

So, to summarize, I'd like a parametric OpenSCAD design that allows me to:

1.  **Customize the heart shape:** I'd like to be able to define the heart's shape via control points or some other method, rather than importing an STL.
2.  **Control the gear ratios:** I need to be able to specify the number of teeth on the gears directly and/or the gear ratio.
3.  **Independently specify the number of turns per cycle:** I want to control this separately from the gear ratio.
4. **Tweak pin dimensions**: I'd like the dimensions of the pin connectors to be parameterized.
5.  **Use MCAD**: I'd like the gear generation to use `involute_gears.scad` from the MCAD library.

I'm not sure if this should be one big OpenSCAD file or multiple files, but let me know what you think. I'm primarily interested in the design aspects right now rather than print settings, so you don't need to worry about tolerances, etc. I'd like to focus on flexibility in the design.

Okay, I'm trying to design a battery holder for standard cylindrical batteries, and I'd like to make it parametric so I can easily adjust it for different battery sizes and arrangements. Right now, I'm thinking of a rectangular grid of battery slots with some reinforcing walls, but I want to be able to change the grid size, battery diameter, and the spacing between batteries.

Specifically, I need an OpenSCAD file that does the following:

*   Takes a few parameters, like `battery_diameter`, `rows`, `columns`, `spacing`, and `height` so that I can easily configure it.
*   Creates a rectangular box as the base of the holder. The size of the box should be calculated based on the number of rows and columns, battery diameter and spacing. The box should also be centered.
*   Cuts out cylindrical slots within the box to hold the batteries, arranged in the specified grid. The slots should have the `battery_diameter` and go through the full `height` of the box.
*   Adds some support structure to the sides of the base box. I'm picturing rectangular walls, or "tabs" along each side of the base box. They should extend slightly beyond the base box. These tabs should also be centered to the base box. The walls should be `height`, but I will want to be able to define a separate `wall_thickness` variable and how much the walls extend beyond the main rectangular box.
*   I would also like the ability to define a battery offset height. I don't want the batteries to sit flush with the bottom of the case, they should be lifted up a bit.

I'm thinking I'd also like some additional parameters for these walls, like `wall_thickness` and `wall_extension`.

I'm not sure if this would work best as a single file, or if you would want to break some things into modules, if that's how openscad works. I don't need anything fancy, but it would be nice to have some room for adjustability. Let me know what you come up with!

[Assistant]
BATTERY.scad:
```

height=31;		//box height
diam=11.5;		//battery diameter
rows=4;
spacing=1;
width=(diam+spacing)*rows+4;

   difference()
  {
			 intersection()
      {
			cube([width,width,height], center = true);
		}

for ( j = [(-width/2)+(width-rows*(diam+spacing))/2+(diam+spacing)/2: diam+spacing : ((width/2))] )
	{
		for ( i = [(-width/2)+(width-rows*(diam+spacing))/2+(diam+spacing)/2 : diam+spacing : ((width/2))] )
		{
			translate([i , j, 2]) cylinder(h = height, r = diam/2, center = true, $fn=20 );
		}
	}
		for ( k = [0 : 3] )
		{
			 rotate([0, 0, k * 90])
				translate([width/2 , width/2, height/2-8/2.1])cube([width*2,1.5,8], center = true);

I'm looking to design a simple, customizable wall hook, and I'd like to do it in OpenSCAD. It's basically a circular base with a hook that extends out from the back. The hook should be angled upwards.

Here are the parameters I'd like to control:

*   **Base Thickness:** The overall thickness of the base circle (which is composed of a larger cylinder and a smaller cylinder on top of it). I need to be able to control the ratio between the two heights, as well.
*   **Base Radius:** The radius of the circular base.
*   **Hook Height:** The length of the hook extending from the base.
*   **Hook Angle:** The angle of the hook relative to the base.
*   **Hook Offset:** The horizontal offset of the hook from the center of the base. This can be a negative value, which would put the base behind the center of the base.
*   **Hook Thickness (Top):** The thickness of the hook at its top end.
*    **Hook Base Thickness:** The thickness of the hook at its base, where it connects to the circular base.

I'd also like to be able to include a simple build plate for scale, using the `build_plate` module from a utils library.

I'm thinking that a file called `Simpel_Haakje.scad` that includes the `utils/build_plate.scad` file would be a good place to start. Let me know if that sounds right.

I'd like to design a parametric cable organizer for my desk. It should essentially be a ring with mounting tabs, and I want to be able to adjust all the dimensions easily.

Specifically, I'm thinking of a circular ring with an adjustable inner diameter. The ring itself needs a definable wall thickness, and it should be extruded along the Z-axis with a variable height/width. I want mounting tabs on opposite sides of the ring, which extend outwards and have holes for screws. Both the length and thickness of the mounting tabs should be adjustable. The diameter of the screw holes should also be parameterized. Finally, I'd like a parameter that lets me choose to have a gap in the ring, as if a small section was removed, or have the ring be complete. If I choose the gap, I need to be able to control its width.

I'm looking for an OpenSCAD file that uses these parameters:

*   `inner_dia`: The diameter of the inner hole of the ring.
*   `wall`: The thickness of the ring's wall.
*   `tab_length`: The length of the mounting tabs extending outward from the ring.
*   `tab_thickness`: The thickness of the mounting tabs.
*   `clip_width`: The height (or width) of the ring along the z-axis.
*   `mount_hole_dia`: The diameter of the screw holes in the mounting tabs.
*   `opening`: A binary switch (1 or 0) to enable or disable the gap in the ring.
*   `opening_width`: The width of the gap if `opening` is set to 1.

I'd also like the resolution of the circle to be definable, maybe with a variable called `fn`.

Could you generate this OpenSCAD file for me?

Hi, I'm looking for help designing a parametric jellyfish model for 3D printing, and I'd like it to be able to make those cool "drooloops" for the tentacles and oral arms. I've seen a design that does something similar, and I'm attaching the code for reference so you can see what I mean.

Specifically, I'd like the following features, with parameters for each:

*   **Jellyfish Body (Bell):**
    *   **Bell Radius:**  Adjustable radius for the main body (e.g., `jf_radius`).
    *   **Bell Height:**  Adjustable height to control the top curve, with the option to make it spherical if the height is equal to the radius (e.g., `jf_height`).
    *   **Support Radius:** Adjustable radius of a central support post where the oral arms are attached (e.g., `jf_support_radius`).

*   **Tentacles (Outer Drooloops):**
    *   **Tentacle Length:** Adjustable length of the outer tentacles (e.g., `jfl_outer_length`). This should influence overall print height too.
    *   **Tentacle Drag:** Adjustable "drag" to control how far down the tentacles extend (e.g., `jfl_outer_drag`).  This influences print height as well.
    *   **Number of Tentacles:** Adjustable number of tentacles per layer.  I'd like to have two layers of these (e.g., `jfl_outer_num`).
    *   **Twist Between Tentacle Layers:** Adjustable twist angle between the two tentacle layers (e.g., `jfl_outer_twist`).

*   **Oral Arms (Inner Drooloops):**
    *   **Oral Arm Length:** Adjustable length of the oral arms (e.g., `jfl_inner_length`).
    *   **Number of Oral Arms:** Adjustable number of oral arms per layer.  I'd like the option to have no oral arms.  Also, two layers are needed (e.g., `jfl_inner_num`).
    *   **Twist Between Oral Arm Layers:** Adjustable twist angle between the two layers of oral arms (e.g., `jfl_inner_twist`).
    *  **Oral Arm Ratio:** A ratio parameter to specify how far up the bottom of the bell the oral arms should extend (e.g. `jfl_inner_ratio`, must be between 0 and 1).

*   **Base Support (Stigma):**
    *   **Stigma Boolean:** A boolean flag (e.g., `stigma`) to turn the base support feature on or off (0 for no, 1 for yes)
    *   **Stigma Number:** Adjustable number of base support points (e.g., `stig_number`).
    *   **Stigma Radius:** Adjustable radius for the base supports (e.g., `stig_radius`).
    *   **Stigma Width:** Adjustable base width of the base support points (e.g., `stig_width`).
    *  **Stigma Height:** Adjustable height of the base support points (e.g. `stig_height`)

*   **Drooloop Parameters:**
    *   **Drooloop Width:** Adjustable width of the drooloop lines, matching the slicer's wall width (e.g., `dl_width`).
    *   **Drooloop Height:** Adjustable height of the drooloop lines, matching the slicer's layer height (e.g., `dl_height`).

I'm hoping for something fairly user-friendly with a modular approach, like in the provided example, that's well-commented so I can understand how it works. I'm not using any external libraries that I'm aware of. I'd really appreciate it if you could generate the whole thing from scratch, and not rely on pre-existing code from the reference.

I'm looking to create a customizable award base, similar to the one described in the provided text. It should have a cylindrical base with a tiered design, where the top tier will have two lines of text wrapped around it. I need this to be parametric, so I can easily change the dimensions and text.

Specifically, I need these features:

1.  **Tiered Cylindrical Base:** The base should consist of three stacked cylinders, with slightly decreasing radii moving upwards, and with the top cylinder being the tallest. The dimensions of each cylinder (radius and height) should be parameters.
2.  **Customizable Text:** The top cylinder should have two lines of text, each of which will be specified as parameters. This text should wrap around the cylinder. The font size should also be a parameter.
3.  **Single or Dual Extruder Support:** I need the design to handle either single or dual extruder printing. For single extruder, the text should be inset. For dual extruder, I'd like separate modules for the base and text so I can print them in different colors.
4.  **Print preview:** I would like the design to render a preview with the correct colors to visualise what a dual extrusion print would look like.
5.  **Build Plate Display:** It would be nice to have an optional build plate displayed for preview purposes, the dimensions of which should also be able to be specified.

I will also need the `write/Write.scad` and `utils/build_plate.scad` libraries for text wrapping and build plate display, respectively. The text wrapping should be handled using the `writecylinder()` function from the `write/Write.scad` library, and build plate display using the `build_plate()` function from `utils/build_plate.scad`.

I'm thinking I will want parameters for:

*   The radius and height of each of the three cylinders.
*   The text for the top and bottom lines of the label
*   The font size for the text
*   The printer type ("preview", "single", "dual1", "dual2")
*   A build plate display selector (like an enum) and if 'manual' is chosen, then the build plate width and depth.

Can you generate an OpenSCAD file (or multiple files, if needed) to handle all of this?

I'm looking to create a customizable box divider for laser cutting, similar to the provided code, but I need it to be more modular and flexible.

The current design uses parameters like `Box_height`, `Box_width`, `Box_depth`, `Wall_thickness`, `Boxes_horizontal`, and `Boxes_vertical`, which is a good start. It also has a `Tab_ratio` which is a good idea. And I see that it even has optional side rails! I'd like to keep all those features, of course.

However, instead of outputting both a flat and assembled version with a single top-level parameter, I'd like to have two main files: `box_divider.scad`, which defines the main pieces and a separate `assembly.scad` file. I'd like `box_divider.scad` to generate the individual flat pieces (the bottom, horizontal dividers, and vertical dividers) all at once, without needing to specify the "flat" parameter, in a layout suitable for laser cutting or printing. It would just output the flattened pieces using a 2D projection. I'd like this file to be fairly 'bare bones' without any logic about assembling parts, other than calculating the positions of parts.

Then, I'd like to create a second file, called `assembly.scad`, which brings in the parts from `box_divider.scad`, and then arranges them into the assembled divider. This file should use the same parameters as `box_divider.scad`. This will let me verify in OpenSCAD that the pieces fit together correctly and easily make variants.

Essentially, I’m thinking of a modular design where `box_divider.scad` handles the creation of flat parts, and `assembly.scad` handles the 3D assembly. This structure will be useful because, later on, I might want to make other parts and assemble them using the same parameters. It also makes it easier to verify that the 2D cutting paths are correct without being confused by the assembly.

I'd also like the following improvements if possible:

1.  **Parametric Tab Shapes**: Instead of just a simple tab, I'd like to specify more complex tab shapes as well, like a rounded tab. I think it would be best if I can pass in an SCAD module as a parameter into the main tab-generating code. So it might be something like `tab_module = "square_tab"` or `tab_module = "rounded_tab"`.

2. **Optional Tab Overhang**: Right now the tabs are cut flush with the edge of the piece. Sometimes I might want to add a bit of overhang to make the fit tighter. There should be a parameter for this.

3.  **Clearer Parameter Names**: Some parameters are a little confusing. Could we use more descriptive names like `box_internal_height`, `box_internal_width`, `box_internal_depth`, `material_thickness`, `horizontal_divisions`, `vertical_divisions`? And maybe `tab_width_ratio` instead of `Tab_ratio`?

4.  **Side Rail Control**: The original design did the side rails with a global option. Instead, I'd like to have an optional `side_rail_width` parameter that is 0 to have no side rails. Then I'd like to have separate flags or booleans `include_vertical_side_rails`, and `include_horizontal_side_rails`.

5. **Use of Modules:** I'd like the design to be built using reusable modules where possible, to make it easy to customize parts individually.

I think the whole thing could be done without libraries, as the original did. Could you provide me with a set of files that implements these changes? I'd appreciate a well-commented design!

I'd like to design a parametric grassy knoll in OpenSCAD, similar to the one described in the provided text and code. I'm looking for a design that will generate a small hillock with a randomized grass covering and the ability to put text on the base. I need the design to be parametric so I can customize things like the size of the knoll, how tall the grass is, and its spacing.

Here's a breakdown of the features I'm looking for:

*   **Knoll Shape:** The base of the knoll should be formed by cutting a sphere with a plane, so the user can specify how "flat" it is by specifying where to cut. The size of the sphere will also need to be configurable.
*   **Grass:** The grass should be generated using a randomized grid-based approach.
    *   The average distance between grass blades should be adjustable.
    *   The width and thickness of each blade should also be adjustable
    *   The maximum height of each blade should be configurable.
    *   Each blade's position, rotation, inclination, and height should be randomly varied within defined limits.
*   **Text:** I need the ability to add text to the bottom of the knoll. The text, its height, and thickness, etc., should be configurable. I want to use a font specified in a .dxf file. I also need to specify the spacing between characters.
*   **Pot Option:** Optionally, I'd like to be able to cut a cylindrical hole into the top of the knoll to make it into a pot. The diameter of this hole should be configurable.
*   **Removal Key:** Include a small key on the base to help with removing the printed object from the build plate.
*   **Build Plate:** It would be helpful to include a configurable build plate for display purposes, where the size of the build plate can be specified.
*   **Libraries:** The design should use the `Write.scad` library for the text and the `build_plate.scad` library for the build plate.

I'd like to have all of the parameters exposed so I can easily adjust them in the customizer. Could you generate the necessary OpenSCAD files for this?

Hey, I'm looking to generate a signet ring design, and I think OpenSCAD is the right tool. I've got some specific requirements, so I'm hoping you can help generate the code.

Basically, I want a ring with a flat top where a single block letter symbol will be embossed or engraved (I'm not sure which yet; that might be something I'll tweak later). I want to be able to specify the US ring size, or alternatively, the inner diameter in millimeters, and have the ring scale appropriately. I need to use the MCAD library, specifically the `bitmap.scad` portion to generate the letter. I'll need to be able to set the letter, its rotation, and whether it is mirrored for printing/stamping. Finally, I'd like to control the tilt angle of the ring - mostly for ease of printing.

Here’s a more detailed breakdown:

*   **Ring Sizing:**  I need to be able to specify a US ring size, and it should calculate the inner diameter based on the table provided in the code I have. If I specify a `RING_DIAMETER` explicitly, that should override the ring size calculation.
*   **Letter Symbol:** The design should use the `bitmap.scad` library to generate a block letter. I should be able to set this to any capital letter.
*   **Symbol Customization:** I need to be able to adjust the symbol's height relative to the ring's flat surface, its rotation, and also if it's mirrored along its Y axis for stamping.
*  **Ring Shape:**  The main ring should be a cylinder that's cut out with another cylinder to make the hole for the finger. Then the edges should be rounded to make them more comfortable. Finally, it should have a flat circular spot for the symbol, made using a sphere subtraction.
*   **Tilt Angle:** I need to be able to rotate the entire ring around the x axis so it prints easier when tilted.
*   **Customization:**  I should also be able to change the `$fn` to adjust the segments per circle.

I'd like this to be a parametric design, so I can make changes without having to rewrite any code. Please generate the OpenSCAD files that I will need. Thanks!

Hey, I'm looking to create a customizable rack system in OpenSCAD, and I'd like to base it on something similar to what I've seen before, but with a few tweaks.

The core idea is a grid-like rack with different sized compartments or "drawers." I need to be able to control how many of each of these compartment types I have, and they should stack vertically. Specifically, I'm envisioning four different sizes: half-height, standard height, double-width, and quad-width.

Here's how I see the basic structure working:

*   **Rows:** I want to specify the number of rows for each compartment type. So, I can say I want 2 rows of half-height compartments, 1 row of standard height compartments, 0 rows of double-width compartments, and 1 row of quad-width compartments.
*   **Compartment Dimensions:**
    *   Half-height compartments should be 31mm wide and about 14.25mm high with some internal cutout leaving a 1mm lip on each side of the compartment.
    *   Standard compartments will be 31mm wide and about 28mm high again with an internal cutout leaving a 1mm lip.
    *   Double-width compartments will be 61mm wide and 28mm high with similar cutouts and lips to the smaller compartments.
    *   Quad-width compartments will be 121mm wide and 28mm high with similar cutouts and lips to the smaller compartments.
    * The depth of the compartments should be variable and specified globally so that they all have the same depth.
*   **Placement:** These compartments will be placed on a grid system in the X-Z plane. The X-spacing between compartment locations will be fixed. The first set of half height compartments should all be aligned to Z=0. The rest of the compartment types should then stack vertically on top of each other.
*   **Overall Height:** The overall height of each compartment should be a global parameter, to make changing the Z height of each compartment and cutouts easier.

Also, I'd like the option to add mounting clips to the top and/or bottom of the rack. These clips should have a sort of a "C" shape, so multiple racks can connect together using these mounting clips.

I will need to have several parameters to control this design. I will need the following:
*   `half_row` : the number of half height rows
*   `normal_row`: the number of normal rows
*   `double_row`: the number of double width rows
*   `quad_row`: the number of quad width rows
*   `height`: the overall height of each compartment
*   `topclip`: a boolean for the presence of the top clip
*   `btmclip`: a boolean for the presence of the bottom clip
*   `depth`: the depth of the compartments

I'm thinking this will require a few modules.
* `grid()` this module will position all of the compartments and clips.
* `half_box()` this module will create the half height compartment.
* `box()` this module will create the standard compartment.
* `double_box()` this module will create the double width compartment.
* `quad_box()` this module will create the quad width compartment.

I'm not too worried about the exact internal structure of the clips, as long as they can connect together. So that can be a pretty basic c-channel shape. I think that's it for now. It would be great if you could generate the OpenSCAD code for this, and I would prefer to have a single .scad file with all of the necessary modules, no libraries needed.

//Quad width row(s)

Hey, I'm looking to create some customizable storage drawers for a rack system I have. I've got an existing SCAD file (BinV1.7.scad) which I've included here, but it's not very flexible and I'd like to build something more parametric from scratch.

The core idea is to have drawers that fit into a rack with a specified depth. I want to be able to choose between a few different box heights: half-height, standard, double, and quad height, and I want an option to include a divider down the middle. Also, I need an option to render just the front divider panel (for labels, I guess), without the entire box.

Here are the things I'd like to parameterize and have control over:

*   **`box_type`**: This would be an integer to select the box height.
    *   `0`: Half height
    *   `1`: Standard height
    *   `2`: Double height
    *   `3`: Quad height
*   **`depth`**: The depth of the drawer, matching the rack it's going into.
*   **`divider`**: A boolean (0 for no, 1 for yes) to enable or disable the center divider.
*   **`panel`**: A boolean (0 for box, 1 for just the divider panel) to choose what is rendered.

Additionally, the drawer should have a finger pull cutout at the front, which the included SCAD file has. And as mentioned in the description, there should be a label holder area at the front. I would like the label area to be rectangular, with the length being slightly shorter than the entire width of the face of the drawer. The width of the label holder should be around 1.5 mm (or maybe 2mm if 1.5 is too fragile).

I'd like the drawers to have a consistent thickness all around.

I don't have any specific requirements on the libraries to use, but I am familiar with OpenSCAD and I don't need any special code for the label SVG.

Could you help me generate a parametric OpenSCAD file for this?
