I'd like a customisable box that can be attached to a metal surface using magnets. The basic shape should be a rectangular prism, but I want the option to round the edges. I need to be able to adjust the inner dimensions (width, height, and depth) and the wall thickness. I want to be able to specify how many magnets are used, and their diameter and depth. I'd also like the option to add a text label to the front of the box, with adjustable font size and font type.

Here are the specific parameters I need to control:

*   **Inner width:** A numerical value allowing me to control the internal width of the box
*   **Inner height:** A numerical value allowing me to control the internal height of the box
*   **Inner depth:** A numerical value allowing me to control the internal depth of the box
*   **Wall thickness:** A numerical value allowing me to specify the thickness of the box walls
*   **Magnet diameter:** A numerical value allowing me to control the diameter of the magnets to be used
*   **Magnet depth:** A numerical value allowing me to control the depth of the magnet holes
*   **Number of magnets:** An integer allowing me to choose between 1 and 5 magnets
*   **Rounded edges:** A boolean allowing me to choose if the edges of the box are rounded
*   **Text label:** A boolean allowing me to add a text label to the box
*   **Label text:** A string that represents the text of the label
*   **Font size:** A numerical value allowing me to control the size of the font of the label
*   **Font type:** A string that represents the font type of the label

I'd like the magnet holes to have a small amount of slack built in (+0.25mm) and I'm assuming the holes will be cylindrical. The rounded edges should be implemented with a hull operation, I think, and the radius of rounding should match the wall thickness.  I'm okay with a relatively low `$fs` setting for fast previews, but a high `$fn` value for final renders.

Could you generate an OpenSCAD file that implements this functionality, or a set of files if it makes more sense to structure it that way? I'm assuming no external libraries are used.

I need a custom control horn for RC plane ailerons and flaps that uses a steel rod servo system. I want it to be parametric so I can easily adjust it for different planes and setups.

Here are the key features I need:

*   **Main Body:** A flat, elongated piece with a specified thickness, height, and length.
*   **Triangular Cutouts:** The long edges of the main body should have triangular cutouts for weight reduction and a bit of style. I need to control how far these triangles are from the top and bottom edges, as well as the distance between them.
*   **Control Rod Attachment:** There should be a circular hole at a specific x and y coordinate for the control rod attachment. I need to specify the radius of the circle.
*   **Attachment Points:** I need to specify the x-coordinates of two attachment points to the main body. These points will be used to connect the control horn to the control surface (aileron/flap).
*   **Optional Attachment Holes:** I need the option to add a small hole at the control rod connection point. This should also have a customizable radius. It'll be a boolean on/off, so I should be able to add/remove the hole by a simple true/false statement.

Specifically, I'd like these parameters to be configurable:

*   `control_horn_thickness`: Thickness of the main body.
*   `control_horn_height`: Height of the main body.
*   `control_horn_length`: Length of the main body.
*   `triangle_margin_top_bottom`: Distance between the triangles and the top/bottom edges.
*   `triangle_margin_left`: Distance between the triangles and the left edge.
*   `control_rod_circle_radius`: Radius of the circle for the control rod attachment.
*   `attachment_pos_left`: X coordinate of the left attachment point on the main body.
*   `attachment_pos_right`: X coordinate of the right attachment point on the main body.
*    `attachment_hole`: Boolean to enable/disable the attachment hole.
*   `attachment_hole_radius`: Radius of the optional attachment hole.
*   `control_rod_xpos`: X coordinate of the control rod hole's center.
*   `control_rod_ypos`: Y coordinate of the control rod hole's center.

I'm expecting the design to be generated using OpenSCAD with these parameters. Make sure the design is cleanly written, easy to understand, and doesn't rely on any external libraries.

Hey! I'm looking for an OpenSCAD design for a toilet brush holder. I've got a couple of brushes lying around and I need something to keep them upright and contained.

I was thinking something pretty basic, like a cylindrical holder that tapers slightly from bottom to top. The bottom should be a bit wider than the top. I'd like it to be parametric so I can tweak it to fit different sized brushes.

Here are the parameters I'm thinking about:

*   `brush_radius`: The radius of the brush itself (or the widest part).
*   `brush_height`: The height of the brush bristles.
*   `holder_thickness`: The thickness of the wall of the holder.
*   `holder_height`: The overall height of the holder.

I'd like the holder to be a simple cylinder with a slightly wider bottom radius. Let's say the `holder_top_radius` is just `brush_radius + holder_thickness`. For the bottom, make the `holder_bottom_radius` something like `brush_radius * 1.1 + holder_thickness` so it widens a little. And the `holder_height` should be just a bit taller than the brush itself, maybe `brush_height + holder_thickness`.

Also, could we add a small rounded lip at the top of the holder? Maybe a 1/2 wall thickness rounded extrusion?

I'd like the resolution to be controlled by a variable `fn` also, but that can be hidden from the user.

I'm also trying to keep it fairly simple, no complex shapes or anything. It's going to be 3D printed, so we'll need to keep that in mind with overhangs.

I don't need anything from libraries. I really just need the single .scad file.

I'm also aware that 3D printed objects aren't watertight. I'm planning to paint the inside to help with that a bit and make it easier to clean. Thanks!

I'd like to design a parametric container for some small metal saw blades. The container should have two parts that slide together, basically a box and a lid. I need to be able to adjust the inner dimensions, wall thickness, and the clearance between the lid and the box.

Specifically, the container should have parameters for:

*   `innerWidth`: The inner width of the container.
*   `innerDepth`: The inner depth of the container.
*   `innerHeight`: The inner height of each half of the container (so the total height will be roughly double this).
*   `wallThickness`: The thickness of the container walls.
*   `clearance`: The clearance between the outer wall of the bottom half and the inner wall of the top half, on each side.

I also want to be able to optionally include a raised label on the top part of the container. The label should have its own parameters:

*   `useLabel`: A boolean to enable or disable the label.
*   `label`: The text of the label.

The label should be raised slightly and sized so it fits well on the container top. I'd like the label to have some kind of backing so the text doesn't fall off if I print it with a color change. It'd be awesome if the text could be centered on that backing.

Could you design this for me? The design should be fully parametric and create two interlocking parts with an optional label. I'd prefer to keep the OpenSCAD code as simple and readable as possible, but feel free to use established libraries if it makes sense. I don't need libraries for complex geometries or anything, but if there's one that does useful things for text handling or general solid operations, I'm open to it.

I need a set of customizable ladders for my tabletop gaming terrain, and I'd like to take the design I already have and expand upon it.  Basically, I want to be able to specify the height of the ladder, and have it generate with the appropriate number of rungs.  The current ladder code I have is very simple: it's essentially two parallel uprights with rungs spaced evenly between them.

Here's the basic structure I have so far:

*   The ladder has two vertical "legs" (rectangular prisms) that are each 2mm x `height` x 2mm. These legs are spaced 13mm apart (so the outer edges are 15mm apart).
*   Rungs are rectangular prisms (15mm x 2mm x 1mm)
*   The rung calculation is a little complicated, but the goal is to leave 3.5mm at both the top and bottom of the ladder legs. Then, I have a total space available for rungs. I want each rung to have 2mm in height, and have at least 2mm between each rung.
*   The number of rungs is rounded down from the available space
*   The spacing between rungs is calculated from the space left after fitting the rungs.

I'd like some improvements to this design, though. Here are the things I'm looking for:

1.  **Parametric Width:** I would like a parameter to specify the width of the ladder (not just the legs themselves, but the entire width from left-most edge to right-most edge). Let's call this parameter `width`.
2.  **Parametric Leg Depth:** Let's call the depth of the legs `leg_depth`. It should be an adjustable parameter. The width of the legs should still be 2mm.
3.  **Parametric Rung Depth:** I'd like to be able to adjust the depth of the rungs as well.  Let's call this `rung_depth`.
4.  **Rounded Rungs:** Instead of sharp rectangles, I'd prefer if the rungs were rounded, like rounded rectangles. I'd like a parameter for the radius of these rounded edges, called `rung_radius`. The rung should still be sized to fit within the total space.
5.  **Rounded Legs:** The same rounding should be applied to the legs (also using the `rung_radius` parameter).

So, the parameters I expect to use are: `height`, `width`, `leg_depth`, `rung_depth`, and `rung_radius`.

I'd also like to have a function that accepts these parameters and generates the full ladder.

I think that's everything. Could you help me out with generating the OpenSCAD files for this? I do not have any external libraries set up at the moment, so please make sure all the code is self contained.

    rungs = round(space/5);
    spacing = (space - (rungs*2)) / rungs;
    translate([0,3.5,2]) {
        for (b = [0:rungs]) {
            translate([0,(2+spacing)*b,0]) cube([15,2,1]);

I'd like to create a 3D printable model of the France Insoumise logo, and I'd like it to be parametric so I can easily change its size, thickness, and add an optional hole for a keyring.

I need the following parameters:

*   `epaisseur`:  The thickness of the logo in mm. This should default to 1mm, and have a range from 0 to 10 in 0.5mm increments. If it is set to 0, it should generate a 2D version of the logo.
*   `diametre_trou`: The diameter of the hole for a keyring in mm. It should default to 1mm.
*   `hauteur`: The height of the logo in mm. It should default to 50mm, and have a range from 10 to 100 in 2mm increments.

The logo itself is a 2D shape that is essentially a filled polygon defined by a bunch of coordinates. Here's that polygon data:

I'd like to design a customizable drink clip, like the one I saw on Thingiverse. It should be a clip that goes on the rim of a glass, with a name on it.

Here's what I'd like to be able to customize:

*   The number of clips to generate.
*   The text for each clip; I'd like to be able to provide a string with names separated by semicolons.
*   The overall length of the clip.
*   The width of the clip.
*   The thickness of the clip material.
*   The distance between the clip arms (i.e., how wide it opens).
*   The height of the extruded text on the clip.
*   The font used for the text.
*   The text font size.
*   The size of the character on the back side of the clip (just a single initial).
*   The spacing between letters in the text.
*   The thickness of the "bubble" around the text.
*   The height of the short arm nubs.
*   The number of short arm nubs.
*   The height of the long arm nubs.
*  The number of long arm nubs.
*   Whether the nubs are offset and how much.
*   The number of arc segments to use when drawing circles (for smoothing).

I want the clip to have rounded inside corners where the arms meet the main body, and I'd like some grippy nubs on the inside of the arms. I'd also like the back of the clip to have a single letter on it, the initial of the name on the front.

Could you create an OpenSCAD file that can do all of this? I'm not using any custom libraries for this one.

Alright, I'm looking to create a customizable wall-mounted spool holder for 3D printer filament, similar to what I have already made (Customizable_Spool_support_Wall_Mount_V1.scad), but I need a complete rewrite that is easier to manage and more versatile.

Here's what I need:

**Core Functionality & Parameters:**

*   **Spool Dimensions:** The design must be fully parametric, with user-defined variables for:
    *   `spool_diameter`: The outer diameter of the filament spool.
    *   `spool_width`: The width (thickness) of the filament spool.
    *   `spool_hole_diameter`: The diameter of the hole in the center of the filament spool.
*   **Mounting Base:**
    *   A flat base that mounts to the wall, with adjustable thickness, perhaps `mount_thickness`.
    *   Two mounting holes to fix the wall plate. The distance between these and their distance from the bottom of the plate should be defined by the parameters `hole_spacing` and `hole_height`.
*   **Support Arm/Portee:**
    *   A horizontal arm extending from the base to support the spool. The length of this arm should be automatically calculated to suit the spool dimensions but I need to be able to manually set the clearance between the spool and the wall with the parameter `clearance`.
    *   Arm should have a defined thickness (`arm_thickness`) to set its vertical size
*   **End Stop/Butée:**
    *   A small vertical piece at the end of the support arm to keep the spool from sliding off. Thickness of this `end_stop_thickness` should be set and its hight, `end_stop_height` should also be customizable.
*   **Reinforcement/Renfort:**
    *   A diagonal brace running from the base to the support arm for added strength.
    *   The angle of this brace should be derived from the support arm dimensions and a user defined parameter `brace_offset`, specifying the vertical position from which the brace should start on the wall.
    *   The thickness of this `brace_thickness` and its width `brace_width` should also be defined parameters.
*   **Fillets:**
    *   I'd like to add fillets to the design for strength and better look, which can be controlled by 2 parameters: `fillet_radius_base_arm` and `fillet_radius_arm_support` for base/arm junction and arm/support.
*   **Units:** Use millimeters for all measurements.

**General Requirements:**

*   **Clean Code:** Code should be well-commented and easy to understand. I'm still learning OpenSCAD.
*   **Modularity:**  Use modules to separate different parts of the design, making it easier to modify in the future, such as the wall mount base, support arm, end stop, and reinforcement brace.
*   **Preview:** I would love to have a good initial rendering to preview the design in different orientation.
*   **No specific libraries are required, all from scratch**

I think that should be enough to get me started. I'm excited to see what you come up with!

Hey, I'm looking to get some OpenSCAD code to generate a customizable wall mount. I've been using a design I made for a tissue box, but it's kind of hacked together, and I want something more robust and easier to use.

Basically, the mount should hold a box-like object and have screw holes for attaching to a wall. I need to be able to adjust the following:

*   **Box Depth (d):**  The depth of the box or object that the mount will hold, let's say from 10mm to 200mm.
*   **Mount Height (h):** The height of the mount itself from 10mm to 200mm
*   **Mount Width (w):** The width of the mount pieces, from 10mm to 200mm.
*   **Mount Thickness (t):**  The thickness of the mount material itself, from 1mm to 20mm.
*   **Screw Head Size (s):** The diameter of the screw heads to be used, from 1mm to 20mm
*   **Screw Size (m):** The diameter of the screw shaft, from 1mm to 10mm.
*   **Counter Sink (sink):** A boolean toggle (1 or 0) whether to use counter sink screw holes or not.

I need the mount to consist of two "C" shaped pieces, one on each side of the box, that are screwed to the wall, with a defined gap between the two pieces that is big enough to hold the box/object, and these parameters need to be customizable. The screw holes should be placed on the vertical parts of the "C" at both the top and bottom, and should either be a normal screw hole, or a countersunk hole based on the boolean above.

I also need to have small supports at the front of the "C" shape to give the mount additional stability.

I'd like a good level of detail for the circles and rounded corners, so I'd like that to be adjustable. Can you also use a function for the rounded corners? Something that will make the corners rounded based on a defined radius parameter.

I'm not sure if any standard libraries are needed, but I'd prefer to have everything built within a single file. I don't need any specific libraries.

Okay, I'm looking to create a custom, handheld electronics enclosure, and I'd like to use OpenSCAD to do it parametrically. I've been using a design, "WLS_LCO_handheld_box_rev_1.4.scad", as a reference, and I'll describe what I need it to do.

The design is for a box that's meant to house a microcontroller, a keypad, an LCD, a battery charging circuit, and a battery pack. It has a base, a top lid that includes a mounting area for a keypad, and an angled section for the display. The whole thing should be parametric so I can adjust the size and other features as needed. Here's a breakdown of the requirements and the kind of flexibility I need:

**Overall Box Structure:**

*   **Three Main Parts:** A base box, a top lid (with keypad mount), and an angled top section.
*   **Parametric Dimensions:** I need to be able to specify the length, width, and height of the base, the length of the angled top in its flat configuration, the height of the top, and the angle of the angled top.
*   **Corner Radius:** The corners of the box should be rounded, and I'd like to specify both the resolution of the round and the radius.
*   **Shell Thickness:** I should be able to control the thickness of the shell.
*   **Lip Height:** There should be a small lip where the top and base join, and I need to control this height as well.
*   **Slop/Clearance:** I need a parameter to adjust the clearance for cutouts and fit of different parts.
*   **Locking Tabs:** Internal locking tabs should have their thickness and diameter controlled by parameters as well as the diameter of the "bulge" on those tabs for locking the parts together.

**Specific Component Cutouts (and the components themselves for reference):**

*   **Keypad:** The keypad should mount to the top lid, and I should be able to specify the keypad's length, width, height, number of rows and columns of keys, as well as be able to add text to each key (if desired).
*   **LCD:** Cutout for an LCD display.  The LCD has its own parameters for the display-only dimensions, the overall dimensions, and the height of both, and should have provision for a screw mount. The display is placed on the angled top with an angle adjustment.
*   **Charger Board:** The cutout for a charger board with parameters for the display area's dimensions and the overall board dimensions and heights.  Like the LCD, this should be placed on the angled top with an angle adjustment.
*   **Power Switch:** Cutout for a power switch with parameters for its length, width and height. Like the LCD and charger, the power switch should be on the angled top.
*   **Battery Pack:** The battery pack parameters include the pack's overall length, width, and height.  The battery diameter and length should be controllable to simulate a 4-cell 18650 pack.

**Additional Features:**

*   **Text:** I should be able to add text to the keypad and the LCD, controlling font and text content.
*   **Hand Grips:** The sides of the box should have serrations to act as hand grips, controlled by the number of grips and their inset.

**General Requirements:**

*   **Parametric Design:** Everything should be driven by parameters so I can easily adjust dimensions without having to edit specific values all over the code.
*   **Modularity:** The code should be modular, with clear separation of concerns for each part of the box and its features.
*   **Print Layout:** It would be good if the code can arrange the three printed pieces for a single print platform and also allow individual parts to be printed separately.
*   **Comments:** The code should be well-commented to explain the different parts and parameters, making it easier to customize in the future.
*   **Libraries:** If needed, I would prefer to use the BOSL library.

I am hoping that the final output will provide three separate SCAD files for the three print sections. I would also like for the base box to have a divider for the battery pack.

I think that's about everything. Let me know if you have any questions.

Wireless Launch System LCO controller case 1.2 March 2017
David Buhler (Crayok)

Custom box design for PIC microcontroller & Board, keypad,
4x20 display, li-ion charge circuit, 4 18650 li-ion battery pack
and a 900Mhz modem.

Project Pics here:
https://www.flickr.com/photos/crayok/albums/72157604233331535

There are only three items printed, Base box that will hold the
controller, modem and batteries with the top lid lower section
housing the keypad that mounts from the bottom side (keypad
flange inside box) There are two hole in this lid that are used
to link the lid to the LCD display and angle section.  The angle
section is variable in angle and length to accommodate the
required display and function stuff.

Adding the extra detail for the inside components gives and idea
how the things will fit and any potential interference.  This allows
for adjustment of the components and the resulting cut-outs to be
accurate.

*
*********************************************************************************
r 1.2Added slop adjustment to top box for better fit
r 1.3 Cleaned up offset code for cutouts
r 1.4 auto adjust print layout corrected,  added extrude for text but also
removed text creation for print part render (save compute power)
adjusted top auto placement as slope changes
