Hey, I'm looking to get a parametric watering can rose designed for 3D printing. I'm using an FDM printer, so the design needs to be printable without supports. The base should be flat for easy printing. I'd like to be able to customize the size, hole count and position.

Here's a breakdown of what I need:

**Overall Shape:**
The rose will have a generally conical shape, leading to a cylindrical spout fitting. It should be a hollow object that water can pass through to the output holes.

**Customizable Parameters:**
*   `WATERING_CAN_SPOUT_DIAMETER`: Diameter of the cylindrical part that attaches to the watering can spout.
*   `WATERING_CAN_SPOUT_DIAMETER_TAPERING`: How much to reduce the cylinder before it gets to the watering can spout.
*   `WALL_THICKNESS`: Thickness of the walls of the rose.
*   `WATERING_CAN_SPOUT_LENGTH`: Length of the cylindrical part that attaches to the watering can spout.
*  `ROSE_LENGTH`: Overall length of the conical part of the rose.
*   `ROSE_DIAMETER`: Diameter of the wide end of the conical part of the rose.
*  `ROSE_HOLES_DIAMETER`: Diameter of the individual spray holes.
*   `ROSE_HOLES_1_QUANTITY`, `ROSE_HOLES_2_QUANTITY`, `ROSE_HOLES_3_QUANTITY`, `ROSE_HOLES_4_QUANTITY`: Number of holes in each of four rings. I might not use all four rings, so make them optional.
*  `ROSE_HOLES_1_DISTANCE`, `ROSE_HOLES_2_DISTANCE`, `ROSE_HOLES_3_DISTANCE`, `ROSE_HOLES_4_DISTANCE`: Distance of each ring of holes from the center of the rose head.
*  `ROSE_HOLES_1_ANGLE`, `ROSE_HOLES_2_ANGLE`, `ROSE_HOLES_3_ANGLE`, `ROSE_HOLES_4_ANGLE`: Angle of the holes relative to the surface of the rose.

**Specifics:**

* The holes should be angled outwards to spread the water.
* The rose should be printable without supports and must have a flat base.
* The design needs to be parametric in OpenSCAD, so all of the above should be parameters.
* I'd like to use `$fn` to make the curved surfaces smoother.

Can you generate the OpenSCAD code for this? I don't want to have to attach any additional libraries. Thanks!

Hey, I'm looking to get some OpenSCAD files created to help me with a project. I need a dummy battery for my Nikon Coolpix P610 camera, specifically an EN-EL23 dummy. The idea is to replace the standard battery with this dummy, so I can power the camera with an external power source. I've actually already got a basic design roughed out in an existing SCAD file, which I'll paste below, but it's not parametric enough and I want it redone with better handling of the dimensions. I'm looking to use parameters that I can change so I can potentially use this for other batteries in the future with some modifications.

The main thing I need is a proper parametric definition of the main body. The current version uses a combination of cylinders and a cube, but I think it might make more sense if it was a single object with rounded edges.  Also, the parameters for the contacts could be a bit cleaner - maybe use an array or list for the x positions? And is there a better way to handle the cable path? I'd like to make that a hole rather than a visual thing. Oh, and could you make the text an optional parameter? It'd be nice to be able to turn that off. Finally, please use the BOSL2 library, as I've already got that installed and I'd rather not include an entirely new one.

Let me know what you come up with!

Hey, I'm looking to create a custom cookie cutter and I'd like to use OpenSCAD to make it parametric so I can easily change things later. I've seen a design I like on Thingiverse (thing:4918969), and it has a lot of the functionality I want, but I'd like to create it from scratch.

Here's what I need:

**Basic Features:**

*   **Border Shape:**  I need to be able to choose between a circle, a rectangle with rounded corners, or a polygon with a configurable number of sides, or upload an SVG to be used as a border.
*   **Border Size:** The size of the border should be configurable. For circles and rectangles, I'll want to set width and height. For polygons, I want to be able to specify the diameter, inside diameter, or side length, and a number of sides. For SVG borders, I should be able to scale the SVG to the desired size.
*   **Rounded Corners:** For rectangles and polygons, I'd like a setting to control the corner radius for rounded corners.
*   **Cutter Height:**  The cutter needs a configurable overall height.
*  **Cutting Edge:** The edge of the cutter where the cookie is cut should have a setting to make it flat or angled.

**Text Features:**

*   **Text on Cutter:** I want to be able to add multiple lines of text inside the cookie cutter shape, but this should also be optional.
*   **Text Settings:** I need options for text size, font, horizontal alignment (left, center, right), spacing between letters, text direction (left-to-right or right-to-left), and line spacing.
*   **Text Positioning:** I also need to be able to nudge the text left/right and up/down, as well as rotate it, for more control over its placement.
*  **Text Support:** Since the text will have a height, I'll need a way to include support bars to keep the text in place. These should be customizable (height, width) and I'd like to be able to optionally hide these in the preview. It should also have the option of using a hull to connect the text with the supports.
*   **Multiple Fonts:** I want an advanced option to use a different font for each line of text. If a font for a specific line is not set, it should use the default font setting.

**Other Parameters:**

*   **Cutter Thickness:** I need two settings here: thickness of the top part of the cutter and thickness of the bottom cutting part of the cutter.
*  **Distance From Cookie:** I also need a setting to control the distance of the text from the base of the cookie cutter.

**Libraries:**

*   I'd like the rounded polygon implementation to use the `roundedRegularPolygon` module from that GitHub repo (https://github.com/AVHon/roundedRegularPolygon/blob/master/roundedRegularPolygon.scad). I don't know if it's its own library, but it would make it easier for me to implement that part.

I think that covers everything.  Could you generate the necessary OpenSCAD files to implement this? I'm looking for a fully parametric design that's easy to modify.

Hey, I'm looking to create a customizable sliding puzzle, kind of like the classic 15-puzzle but with some flexibility. I've been having some trouble printing existing designs, and I'd like something that I can tweak a bit.

Ideally, the design should have these core features:
*   **Adjustable Grid:** I need to be able to specify the number of rows and columns for the puzzle grid.
*   **Customizable Text:** Each square should have text on it, which I can change and specify the font/size of.
*   **Frame Generation:** The frame around the squares should be automatically generated and sized based on the square grid.
*   **Print Friendly:** The design needs features to help with printing, such as chamfered edges on the squares to reduce elephant's foot and adjustable gaps between the frame and squares.
*   **Parametric:** All of these settings need to be able to be defined via variables at the top of the code, and automatically adjust the puzzle size and all of it's pieces.

The included puzzle.scad uses some good ideas I'd like to keep, namely:
*   the chamfering of the inner pieces
*   the basic layout of a cube with other subtractions to achieve the look
*   use of a boolean array to choose whether or not to include a piece (that is, there's always a blank space)

I'd like to use the BOSL library for this, as that seems to provide a lot of helpful functionality that I was using in the included code. I don't need you to provide the BOSL files themselves as I already have them. Specifically, I'm using the `constants` and `masks` modules, so please be sure to use those modules. I'd like to have the file organized with variables at the top followed by the modules and then the implementation at the end.

I'm not set on a particular structure, so feel free to organize things how you think best.

Can you help me generate that OpenSCAD file?

Hey, I'm looking to design a customizable, stackable shelf system using OpenSCAD. I've got some specific requirements, and I'd like you to generate the necessary SCAD files.

The system should be made up of three core parts: a stand, a double stand, and a base plate. Each part should have configurable dimensions and interconnection options to allow for flexible arrangements.

Here are the details for each part:

**Stand:**

*   **Base Dimensions:** This is a stand that's essentially a vertical support, with a rectangular base and a rectangular top. I need to be able to configure the width, height, and depth of this base, as well as its thickness.
*   **Stand Thickness:** I also need a parameter to control the thickness of the main vertical part of the stand.
*   **Stand Base Size:** There needs to be a parameter to control the size of the base of the stand.
*   **Stand Support Width:** There should also be a parameter for controlling the width of the support where the stand latches into the baseplate.
*   **Stacking:** I need to be able to specify whether this part can be stacked on the bottom and/or the top. This will determine whether a latching mechanism is added to the respective ends of the stand.

**Double Stand:**

*   This is essentially two of the standard stands connected together by a support beam.
*   It should use the same base dimensions and thickness parameters as the single stand, including all of the stand parameters.
*   I need to be able to generate two stands with the interconnection between them.

**Base Plate:**

*   **Base Dimensions:** The base plate should have configurable width, height, and depth. There should also be a configurable base thickness.
*   **Connectors:** The base plate should have connection points that will mate with the stands. These connectors will need to have adjustable width, and two heights (small and big).
*   **Walls:** I need to be able to add optional walls to the base plate on any of its four sides, and specify the height and thickness of these walls.
*   **Connectivity:** I need to be able to control whether the base plate has connection points on the left, right, back, and/or front.

**General Parameters:**

*   **Printing Tolerances:** There should be parameters for XY and Z printing tolerances.
*   **Support Overhang:** There should also be a parameter for the support overhang.
*   **Overhang Supports:** I also need the ability to generate automatic overhang supports for the stand if desired.

**Interconnection Logic:**

*   The stands need to be designed to slot into the base plate's connectors. There should be interlocking mechanisms for stacking (vertical) and for connecting base plates to other base plates (horizontal).
*   The horizontal connection between baseplates should allow them to butt up against each other in a grid.

Could you generate these SCAD files for me? I don't have any libraries in mind, so I'm open to your recommendation.

I'd like to design a fruit fly trap, and I want it to be parametric so I can adjust it to different bowls. The basic idea is a lid that sits on top of a bowl, with a cone-shaped entrance in the center leading into the bowl.

Here are the parameters I have in mind, categorized for clarity:

**Basic Parameters:**

*   `bowl_diameter`: The outside diameter of the bowl the trap will sit on. This is the primary driver for the overall size of the trap.

**Advanced Parameters:**

*   `cone_enter_diameter`: The diameter of the cone opening where flies enter. I'd like this to be adjustable, but somewhere around 40-50mm seems good.
*   `cone_height`: The height of the cone. This should be roughly half the cone enter diameter or less, and also less than the bowl height.
*   `cone_exit_diameter`: The diameter of the hole at the bottom of the cone, where flies enter the bowl. Something small like 2.8mm should work.

**Expert Parameters:**

*   `lid_protect_height`: The height of the outer wall of the lid. This creates a small lip to help hold the trap on the bowl. I'm thinking about 5mm.
*   `cone_wall_thickness`: How thick the cone walls should be. About 1mm sounds good.
*   `lid_thickness`: The thickness of the main part of the lid, something like 2mm. This should be a multiple of the layer height for 3D printing, if possible.
*   `air_window_height`: The height of the air windows. These should be narrow, maybe around 0.8mm, and also a multiple of the layer height.
*   `air_window_width`: The width of individual air windows, like 4mm initially.
*   `air_window_pillar_width`: The horizontal gap between the air windows on the same level, something like 3mm.
*   `air_window_vertical_gap`: The vertical gap between air windows, a small amount like 0.6mm, and again, it would be good if this was a multiple of the layer height.
*   `chamfer`: A small chamfer value, around 0.6mm, for the edges of the lid.

I'm envisioning the air windows as cutouts in the cone portion of the trap. They should be arranged in horizontal layers, with a vertical gap between each layer. The number of windows per layer should vary depending on the diameter of the cone at that height. It should be that the windows are close to the `air_window_width` while leaving enough room for `air_window_pillar_width`.

I think that's everything. Could you generate the OpenSCAD code for this, please? I don't think I need any specific libraries for this design.

Hey, I need a customizable T-nut for a woodworking track saw, specifically for the Bosch GTS 10 XC but with adjustable parameters to fit other tracks. I've already got some basic ideas, so I'd like it to have the following features:

First, the T-nut should have a main body, a "table slot" part that fits into the track, and screw holes for attachment. I'd like to be able to specify the overall length, max width, total height, the width of the table slot (the part that slides in the track), the height of the table slot, and a radius for rounded edges to avoid printing issues on hard corners.

For screws, I would like to be able to specify the number of screw holes, the hex screw head diameter and thickness, the screw diameter, and an offset for the hole to be slightly larger than the screw. It's important that the screw holes are evenly spaced along the length of the T-nut, and I'd like to have a parameter to turn the screw holes on or off.

So, overall I need these parameters to be configurable: `length`, `width`, `total_height`, `table_slot`, `table_slot_height`, `edge_cylinder_radius`, `add_screws` ("yes"/"no"), `nr_of_screws`, `screw_head_diameter`, `screw_head_thickness`, `screw_diameter`, and `screw_hole_offset`.

Could you please create an OpenSCAD file for me that does all of this? I don't need any external libraries. Thanks.

I'd like to generate some custom pottery-like vessels, and I'd like a parametric OpenSCAD design that I can use to explore different shapes and patterns.

The basic idea is to have a vessel that is essentially a cylinder or a cone, with the option of adding a lace pattern. I'll need to control the diameters of the top and bottom, the height, the wall thickness, and the thickness of the bottom. Also, it should be possible to specify a number of segments for the vessel's basic shape, to adjust the resolution.

For the lace patterns, I'd like to be able to choose between squares, circles, rhombuses, hearts, triangles, and stars. If none of these are chosen then the vessel will be solid. Each pattern type should have its own size parameter. I'll also need a way to control the minimum gap between the pattern elements, both vertically and horizontally. Also, I need the ability to set an offset, an angle of rotation for the pattern.

The star pattern is a little more complex than the others, so I'll need the ability to specify whether the inside of the star should be cut out, or bars connecting the points of the star to the center to form a more robust print, or no support at all. If bars are used, then I'll need the ability to set the number of bars and their width. There should also be an inner_star_gap parameter.

Finally, I'd like to have the option to add text to the bottom of the vessel, either inside or outside, and either indented or raised. I need control over font size, font type (Liberation Sans by default), bold/italic, and the text height and line spacing and the resolution of text.

It would be helpful if there was a debug mode so that I could check some of the calculations that are done, but this should be disabled by default.

I think that should cover everything, let me know if you need more info. I don't need any libraries, just a .scad file or set of .scad files that implement what I've asked for.

Hi, I'm looking to design a configurable stool using OpenSCAD. I want to be able to adjust the overall size, and have it generate the 2D shapes I need for cutting on a CNC router. I'd like it to be a flat-pack design, so it can be easily assembled.

Specifically, I envision the stool having a rectangular top with rounded corners on the sides, kind of like a racetrack shape, and four legs connected by two support pieces. The legs should connect to the supports with a kind of lap joint and the supports will connect to the top using mortise and tenon joinery.

Here are the parameters that should be configurable:

**Top:**
*   `top_length`: Overall length of the rectangular portion of the top.
*   `top_width`: Overall width of the rectangular portion of the top.
*  `top_thickness`: Thickness of the top material (mainly for 3D display).
*  `top_radius`: Radius of the rounded portion on each of the two ends of the top.
*   `top_radius_offset`: Amount to offset the center of the radius circle in the negative y-direction to create the racetrack shape (this needs to be fine-tuned to have a smooth blend)
*   `top_handle_length`: Length of the optional handle cutout in the top (if any).
*   `top_handle_width`: Width of the optional handle cutout in the top.
*   `top_handle_flip`: A binary option (0 or 1) to switch between a handle along the top's length (0) or along the top's width (1) - zero by default.

**Tabs (for Top to Supports):**
*   `tab_length`: Length of the tenon tabs.
*   `tab_depth`: Depth of the tenon tabs (must be less than or equal to the top thickness).
*   `tab_position_x`: Inset of the tab from the ends of the supports/top.
*   `tab_position_y`: Inset of the tab from the sides of the top.
*   `tab_bit_diameter`: Diameter of the milling bit used for the round ends of the tenons/mortises (set to 0 to disable).
*   `tab_tolerance`: Tolerance added to the mortise width/length to allow for easy fit.

**Long Supports:**
*   `long_support_length`: Overall length of the long support pieces.
*   `long_support_width`: Width of the long support pieces.
*   `long_support_thickness`: Thickness of the support pieces.
*   `long_support_radius`: Radius of the rounded end portion of the long support.
* `long_support_radius_offset`: Offset of the rounded end to form a blended shape.

**Support to Leg Joint:**
*   `support_to_leg_bit_diameter`: Diameter of the milling bit used for the round ends of the lap joints (set to 0 to disable)
*   `support_to_leg_tolerance`: Tolerance added to the width/length of the lap joint overlap.
*   `support_to_leg_offset`: Inset of the lap joint from the ends of the long supports.
*   `support_to_leg_angle`: Angle of the leg relative to the support
*   `support_angle_offset`: a calculated offset based on the angle of the legs and the material thickness of the supports
*   `support_to_leg_overlap`:  How much of the leg overlaps with the long support piece. (this value will be used for the 3d positioning and the actual overlapping dimension will be increased by adding support_angle_offset/2 * long_support_thickness )

**Legs:**
*   `leg_thickness`: Thickness of the legs.
*   `leg_height`: Overall height of the legs.
*  `leg_radius`: Radius of the rounded corners of the legs.
*  `leg_radius_inset`: Inset distance between rounded corners.
* note that the leg width is taken from the `top_width` parameter

I'd like the design to include both an assembled 3D view and also an exploded 3D view, as well as a flattened 2D layout for CNC cutting.  I plan to use standard mm measurements so the code will need to be able to generate all of the cut pieces in 2d (svg or dxf).

I'm not specifying any particular libraries for this one, it should be straightforward enough without any additional tools.

Thanks!

[User]
I'd like to design a parametric bottle cutter in OpenSCAD. I've got some existing design parameters that I want to be able to tweak, as well as some new things I'd like to be able to control. Here's what I'm thinking:

**Core Structure:**

The core is a rectangular box with rounded corners (minkowski sum with a sphere). This box will have a slot cut out of it for the bottle to sit in. This slot should be a circular segment.  The box will also include slots for blades to be inserted. There should be a recessed area for a washer to be inserted which holds the bottle in place.

**Parameters (Existing):**

*   `clearance`:  A general clearance value for holes/slots (e.g., 0.3mm)
*   `wall`: Wall thickness for the box (e.g., 3mm)
*   `base_h`: Height of the base (from the bottom to the washer bottom) (e.g., 5mm)
*   `pre_cut_l`: Distance from the input side of the box to the blade's cutting edge (e.g., 10mm)
*   `blade_width`: Width of the blade (e.g., 18mm)
*   `blade_height`: Height of the blade (e.g., 0.5mm)
*   `blade_height_clearance`: Clearance for the blade height in the slots (e.g., 0.25mm)
*   `cut_widths`: A list of distances from the top of the washer to the middle of each blade slot (e.g., `[4, 6, 10, 15]`). There can be more or less than this.
*   `bottle_slot_width`: Width of the bottle slot (e.g., 3.5mm)
*   `bottle_slot_r`: Radius for the bottle slot arc (e.g., 100mm)
*   `washer_d`: Diameter of the washer (e.g., 14.8mm)
*   `washer_h`: Height of the washer (e.g., 1.2mm)
*   `washer_h_clearance`: Clearance for the washer height (e.g., 0)
*   `depth`: Depth (y-size) of the box (e.g., 45mm)
*   `corner_radius`: Radius of the rounded corners of the box (e.g., 1.5mm)

**New Parameters I want to add:**

*   `blade_slot_depth`: The depth of the blade slot into the body of the cutter. Should be configurable, with the default equal to the 'depth' variable.
* `blade_slot_side_clearance`:  Clearance on both sides of the blade slot in addition to `clearance`
* `blade_slot_vertical_clearance`: Clearance of the top and bottom of the blade slot in addition to `blade_height_clearance`.
*   `washer_side`: an enum which can take values of `"input"`, `"output"`, `"both"`, or `"none"` where `"input"` puts the washer on the side where the bottle enters, `"output"` puts it on the opposite side, `"both"` puts a washer on both sides, and `"none"` doesn't place any washers.

**Desired Functionality:**

1.  **Parametric Design:** All values should be parameters at the top of the file.
2.  **Blade Slots:** Blade slots should be created using a `for` loop based on `cut_widths`.
3.  **Washer Placement:** The code should place washers based on the `washer_side` enum. If `washer_side` is `"both"`, it should put another washer on the opposite side of the cutter, aligned with the existing washer vertically. The depth of the washer hole should be equal to the washer's height + it's clearance, regardless of where the washer is placed.
4.  **Clearances:** I need to ensure that clearances are applied properly to all holes and slots, as well as for the washer hole and blade slots, so it's actually printable.
5.  **Previewable:** The code should render well in OpenSCAD.
6.  **Print orientation:** The model should print with the washer slot facing up so that the blade slots are oriented vertically.
7.  **No libraries**: Do not include any libraries for this design.

Can you generate the OpenSCAD code for this?
