Hi! I'm looking to design a parametric phone tripod that's about the size of a credit card, so it can fit in a wallet. I want it to have slots that will hold the phone at different angles, maybe even overlapping slots for more angle options. I've seen some designs like this where the support structure can also act as a hinge. Ideally it should be adjustable for different phone thicknesses, and the angle of the slots should be adjustable as well.

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

**Overall Dimensions & Shape**
*   Roughly the size of a standard credit card (54mm x 86mm x 0.8mm).
*   Rounded corners on the card itself.

**Phone Holding Slots**
*   Two main slots that hold the phone, adjustable in angle.
*   Ability to add additional slots with different angles that can even overlap the main slots.
*   The depth of these slots should be adjustable based on phone thickness.

**Support / Hinge**
*   A support structure on the card that can both act as a support when the tripod is deployed and also as a hinge point to rotate the support into position.
*   I'd like the support piece to have a slot/cutout that fits into the base card so it's more secure.
*   I want to be able to toggle the support for either a single centrally-placed support, or two supports at the sides.
*   A good place for text on the card is desired.

**Parametric Options**
*   Phone Thickness: Adjustable to fit various phone models/cases.
*   Tripod Base Width: Adjustable width where the phone sits.
*   Slot Angles: Adjustable angles for each slot on the card.
*   Slot Distance: Adjustable distance between the main slots.
*   Slot Height: Adjustable height of the slots.
*   Support Position: Adjustment for the support positions
*   Text: Customizable text on the card.

**Libraries**
*   I’d prefer not to rely on any extra libraries if possible, but if you have to use any external code please use the fillet function from BOSL2.

Could you design this for me? I think it would be a really useful everyday carry item. Thanks!

I'd like to design a coin holder for my car, something that can hold different denominations of US coins. I want it to be parametric, so I can easily adjust things like the number of slots for each coin type, the overall size, and how deep the slots are. I envision a circular base with coin slots arranged around the perimeter.

Here are the specific parameters I'd like to be able to control:

*   **Coin Slots:**
    *   I need to be able to specify the number of slots for each of these coin types: pennies, nickels, dimes, quarters, half dollars, and dollar coins. I'd like to be able to set these to 0 if I don't want any of a certain type.
    *   I also need to be able to control the padding around each coin slot. This is an extra bit of space that gives a little wiggle room for the coin.
    *   The depth of the slots should be adjustable as well. I'd like an option to either set a fixed depth for all slots or have the depth automatically calculated based on the thickness of the coin and how many coins I want each slot to hold. I should be able to specify how many coins I want each slot to hold, as well as the coin type to use when making that calculation.

*   **Labels:**
    *   I want to be able to label the slots. This should have an option to either turn labels off, show the coin's value (like "1" for a penny or "25" for a quarter), or show "pips" (small dots) where the number of pips corresponds to the value.
    *   If I select the value option, I should be able to adjust the font size.
    *    If I select pips, I need to set the diameter of the pips.

*   **Base:**
    *   I need to be able to control the thickness of the base at the bottom.
    *    I also need to control the diameter of the base.

*   **Other:**
    *   I want to make sure I'm controlling the level of detail for all rounded shapes. I'd also like to have a small epsilon value used when subtracting shapes to avoid any orphaned sides.
    * I will also need the diameters, thicknesses, and text values for each coin type.

I think that covers everything. Could you please provide me with the OpenSCAD code for this design?

I need an OpenSCAD design for a customizable organizer, mainly intended for small parts. I'd like to be able to define the size of the individual compartments, how many compartments there are in each direction, and a few other things.

Here's how I'm imagining it. It should be a grid of compartments, all the same size, with walls separating them. I'd like the outer walls to be thicker than the inner walls to provide some robustness. The bottom should be solid, so the compartments are like trays. Also, I want to be able to print it in vase mode (spiralize), so the walls should be a single line thick, except for the bottom.

I need to be able to set:

*   `compartmentSize`: A 3D vector defining the width, depth, and height of each compartment.
*   `compartmentCount`: A 2D vector defining the number of compartments in the width and depth directions.
*   `nozzleWidth`: The width of the extrusion nozzle, to ensure the walls are the correct thickness.
*   `cutWidth`: A small width that will separate the walls to print in vase mode.
*   `layerThickness`: The layer height of the print.
*   `bottomLayerCount`: The number of layers for the solid bottom.

The inner walls should have a thickness of `nozzleWidth` * 2 + `cutWidth`. The outer walls should have a thickness of `nozzleWidth`. The total height should be the `bottomLayerCount` * `layerThickness` + `compartmentSize[2]`. The total width and depth should be calculated based on the number of compartments, the compartment size, and inner and outer wall thicknesses.

I'd like the code to be parametric, so if I change any of those values, it should automatically update the model. I want the generated file to be well-commented, so I can understand how it works.

Can you generate an OpenSCAD file for this? I don't need any external libraries, just vanilla OpenSCAD.

I'd like to design a parametric fruit fly trap that can screw onto different-sized jars. The main body of the trap should be a sort of funnel shape, and the lid portion needs to have threads that will match the threads of a typical jar.

Here are the key parameters I want to be able to control:

*   **`outer_thread_diameter`**: This is the diameter measured across the outside of the jar's threads.
*   **`height`**: The total height of the assembled trap.
*   **`thread_starts`**:  The number of separate thread segments on the lid.
*   **`lid_inner_height`**: The inner height of the lid section, which also determines the thread height.
*   **`fa_final` and `fs_final`**: These will control the rendering detail for final output.
*   **`fa_preview` and `fs_preview`**: These control rendering detail for previews.
*   **`CLEARANCE`**: A small amount of space between the threads of the trap and the jar.
*   **`CHAMFER`**: A chamfer applied to the outer edges for nicer looks and to improve printability.
*    **`RIM_WIDTH`**: The width of the flat inner rim of the trap, inside the threads.
*   **`WALL_THICKNESS`**: The thickness of all walls in the trap design.
*   **`THREAD_DEPTH`**: The depth of the thread profile.
*   **`THREAD_ANGLE`**: The angle of the flat part of the thread profile.
*   **`THREAD_TIP_RADIUS`**: The radius of the rounded tip of the thread profile.
*   **`THREAD_PITCH`**: The distance between threads.
*   **`THREAD_HEIGHT`**: Height of each thread fragment on the lid.
*   **`PERFORATION_HOLE_HEIGHT`**: The height of the perforations on the trap body.
*   **`PERFORATION_HOLE_WIDTH`**: The width of the perforations.
*   **`PERFORATION_DISTANCE_V`**: Vertical spacing between perforation layers.
*   **`PERFORATION_DISTANCE_H`**: Horizontal spacing between perforations.
*   **`ENTRANCE_RADIUS`**: The radius of the hole at the bottom of the trap, where flies enter.

The design should include:

*   A main body with a funnel-like shape.
*   A lid section with threads matching the jar.
*   Perforations along the sides of the funnel, which should get larger at higher levels of the funnel (i.e. closer to the lid).
*   Thread end caps to properly round out the ends of the thread fragments on the lid.

I'd like a single `.scad` file containing the entire design, and I'd prefer not to use any external libraries. Let me know if you have any questions!

Hey, I'm looking to create a customizable magnetic chessboard. I've got some specific requirements for the design and I'd like to use OpenSCAD, if that's doable. I'm thinking of a modular board, made up of corner pieces, edge pieces, and center pieces, along with individual squares. I'd like the flexibility to print different configurations, or even just one type of piece at a time.

Here are the key parameters I need to control:

*   **Square Size (SSize):** This will be the base unit for all other measurements. I need to be able to adjust this to fit different board sizes. For reference, I was using 57.15mm.
*   **Magnet Diameter (DMag):** The diameter of the magnets I plan to use. I need to define the circular cutouts based on this. I was using 12.05mm.
*   **Magnet Height (HMag):** The height of the magnets, to make sure the recesses are the right depth. I was using 2.85mm, plus a little extra for height, maybe +1.
*   **Piece Height (SHei):** The overall height of the pieces. I'm thinking it should be slightly taller than the magnet height. I was using HMag+1.
*   **Part to Build (BPart):** This will be a variable to select which part I want to generate (board, corner, edge, center, square, etc.). This is important for printing different pieces for testing, etc.

I'd like the design to have:

*   **Full Board:** Assembled by combining the different pieces; 8x8 squares.
*   **Corner Pieces:** With a single magnet hole. The corners should also have some nice fillets on their edges.
*   **Edge Pieces:** With two magnet holes, also with fillets along the edges.
*   **Center Pieces:** With four magnet holes, simply a flat square.
*   **Individual Squares:** With a magnet hole, with edge fillets and some extra tolerance for magnets so they're not too tight.
*   **Test Fit Piece (TFit):** A small square with edge fillets and a magnet hole, for testing fit and tolerances. This part should have extra magnet tolerance and should be a smaller square.
*   **Modular Design:** Everything should be created from individual modules to make it easy to use the different parts.
*   **Fillets:** Beveling and filleting the edges of all the pieces would be good for aesthetics and to make them easier to handle.

For libraries, I've used `BOSL` and it seems to have some good functions, especially for transforms and masks, and fillets. Can you generate the SCAD files necessary for this board with the above parameters?

I'm looking for an OpenSCAD design for a customizable tool holder, kind of like an under-cabinet organizer for pliers, wire cutters, and similar hand tools. I want to be able to specify the dimensions of each tool slot individually using a few parameters, and I'd like to use OpenSCAD's ability to iterate over an array of values to generate these slots.

Specifically, each tool slot needs to be defined by the following four parameters:

*   **Top Length:** The length of the opening at the top of the slot where the tool is meant to stop. This will vary based on the tool's size, but I guess it's the widest part of the tool and not the handle.
*   **Bottom Length:** The length of the opening at the bottom of the slot, where the tool's tip or narrower end will rest. This should be less than the top, to hold the tool in. I'd say it's about 90mm down from the top, but can vary if the tool is longer.
*   **Width:** The horizontal width of the slot. This needs to accommodate the tool's thickness, plus a bit of clearance.
*   **Overhang:** Extra space beyond the tool slot's edge to account for handles or any part of the tool that sticks out past where it stops.

The organizer should have a uniform depth (let's say 90mm for now), and I'd like to control the overall wall thickness. It should also have a top plate that runs along the top edge of the slots, which will help hold it together. The angle of the top plate should be adjustable. Finally, I'd like an option for screw holes for mounting. I can choose between edge screw holes which are half holes, so it can interlock with additional organizers, and offset screws.

I'd like to be able to specify all the slot dimensions and the other settings via parameters at the top of the SCAD code. I think I could accomplish the parametric generation and screw holes without using a library, but I'd like it if you could include the ability to import settings via a .json or .csv if possible. If that requires a library, I'd be okay using it.

I'd like a design for a customizable screw-top container, like a small jar with a lid, and a separate ring that sits between the two. It should be parametric, so I can adjust the inner dimensions and some other features.

Specifically, I need to be able to set the inside height and inside diameter of the container. There should also be an option to add additional height to the cap, which effectively increases the total inside height. I want to be able to choose whether the container has a knurled outer surface on both the body and the cap, or a smooth one.

I'd also like an option to "expand the interior" of the container. The standard container should have straight inner walls, but this option should create a stepped interior - with a wider cavity for most of the height, and a narrower neck towards the top.

The ring should sit between the cap and the body of the container. I'd like to be able to add custom text to the ring. Finally, I need to be able to turn rendering of the ring and the main container body/cap on and off independently.

I think that covers all the requirements. Let me know if you need anything else.

Hey, I'm looking to design a customizable screw-top container, and I have a pretty good idea of what I want. I've seen some great examples online, but I'd like to generate my own using OpenSCAD.

Basically, I need a cylindrical body with a screw thread, and a matching cap. I'm thinking the main parameters should be the *inside* diameter and *inside* height of the container. The outside diameter of the body should be 8mm larger than the inside diameter. The overall height of the container should be the inside height plus 12mm.

The body needs a few features. It should have a smooth inner surface for the container part and a threaded area near the top of the cylinder to accept the cap. It should also have a chamfered inner edge at the top of the inner cylinder where it transitions to the threads, and a chamfer on the outer top and bottom edges. I’d also like a knurled outer surface on the lower section of the cylinder, not just a smooth one, for better grip. I'm imagining that knurling as small, vertical bars, and the density and twist of those bars should be parametric.

The cap needs a matching thread, of course, that mates to the body. It also needs a recessed area that fits over the top of the body. The cap should have a lip or bar that prevents it from screwing in all the way to the bottom. There should be fillets at the base of the bar, and it should have a chamfer on the outer top and bottom edges like the base.

It would be really neat if the knurl density and twist were dependent on the inside diameter. I've seen an example where the number of knurling bars was roughly (diameter + 8) * 1.125, and the twist factor was roughly (92 - diameter)/30 + 1.2. I think I'd like to use those as default formulas. I think having the twist be different for each of the knurled bars would be a nice touch.

Could you generate an OpenSCAD file (or files if it makes sense) to create this? I am fine with a single file if you think that is best. Also, please do not use any external libraries. I want this to be as self-contained as possible. I’m really excited to see what you come up with!

Hey, I've got a project in mind and I think OpenSCAD is the right tool, but I need some help with the code. I'm looking to create a parametric print-in-place clamp, kind of like a flexible clip.

Here's the general idea:

It'll have a central spring mechanism made of concentric rings that are connected, and two plates that act as the clamping surfaces. I want to be able to adjust the dimensions of all the parts through parameters. The clamp should be printable as a single piece without supports.

**Specific details and parameters:**

**General:**
*   **Clearance:** A parameter to control the print-in-place clearance between moving parts. Let's start with a default of 0.3mm, but I'd like to adjust this value between 0 and 0.5mm.

**Spring:**
*   **Radius:** The radius of the main spring circle.
*   **Thickness:** The gross thickness of the spring profile.
*   **Layers:** The number of concentric layers making up the spring. Each layer should have a gap between it and the next layer. The total number of layers should be adjustable between 0 and 100 and default to 2.

**Plates:**
*   **Width:** The width of the clamping plates. This also affects the depth/height of the spring/clamp.
*   **PlateThickness:**  The thickness of the clamping plates. This informs the angle of our spring opening.
*   **Gap:** The initial gap between the clamping plates and the central axis, which will directly affect the starting width of the clamp.
*   **PlateExtension:** An optional extension of the lips of the clamping plates.

**Hidden (don't need to be user-adjustable, but should be in code):**
*   `$fs` = 0.5
*   `$fn` = 40
*   `Overlap` = 0.1

**Important details:**
*   The plates should connect to the spring using rods that interlock in a slot to provide a robust, but flexible join.
*   The spring layers should have end caps to provide a robust connection.
*   The code should ensure the entire clamp can be printed as one piece.

I'm not worried about specific tolerances beyond the `Clearance` parameter; I'm mostly after the adjustable core functionality and a solid, print-ready output. I'm not using any specific libraries for this, so hopefully this is okay! Could you please generate the OpenSCAD code for me?

[User] I'd like a parametric cube design in OpenSCAD. The basic idea is that I want to be able to easily change the size of the cube by adjusting a single variable, which should control the length of each side. I'd prefer to avoid any fixed parameters for the dimensions. Could you generate that for me?

I'd like to create a custom vacuum cleaner crevice tool, and I want it to be parametric so I can adjust it to fit different vacuum pipes and specific needs. I've got some ideas about the different features I'd like to control.

First, I need to specify the diameter of the vacuum cleaner pipe, plus a little clearance so it fits easily. I'd like a variable called `Base_Diameter` to control that. Then, there needs to be a section of the tool that overlaps the vacuum cleaner pipe, and I want to be able to set the length of that overlap using `Base_Overlap`. After that overlap section, there should be a chamfered area transitioning to the main nozzle section. I want a parameter, `Base_Chamfer_Length`, to set the length of that chamfer.

The thickness of the material at the base, where it connects to the vacuum pipe, should be adjustable with `Base_Thickness`. And I'd like the base itself to be able to taper, so I need a `Base_Taper` variable, with a positive value making it narrower at the bottom and a negative value making it narrower at the top.

Then, the actual nozzle itself. I need to set the total length of the nozzle, so I need a `Nozzle_Length` variable for that. The nozzle section will have a rectangular shape, and I need two variables for its dimensions, called `Nozzle_Outer_A` and `Nozzle_Outer_B`. The corners of this rectangular shape should have a fillet, controlled by `Nozzle_Fillet_Radius`. I also need `Nozzle_Thickness` to be adjustable for the wall thickness of the nozzle. And finally, I'd like to control the chamfer at the very tip of the nozzle with two variables: `Nozzle_Chamfer_A` for its depth and `Nozzle_Chamfer_B` for its length.

I imagine that the design will be built using a combination of `cylinder` and `linear_extrude`, with a `minkowski` function for the nozzle section with the fillets. I'd like to start with the positive volume of the entire shape, then subtract the inner volume to create the shell. Finally, I'd like the code to be written to gracefully handle cases where the fillet size is larger than the nozzle dimensions, or where the chamfer values result in invalid geometries. For example, the script should adjust the values to ensure that the geometry can be created, and it should output a warning.

Could you generate the OpenSCAD code for this?

Hey, I'm looking to get some help designing a customizable box and lid in OpenSCAD. I've got a basic concept I'm going for, based on an existing design, but want to tweak it and make it easier to use.

Here's what I need: I want to be able to specify the inside dimensions of the box (length, width, and height), the wall thickness, and then have a lid that fits nicely on top. The box should have rounded corners - like a pill box, I guess. The lid should have a bit of an overhang, and I'd like to be able to engrave text on top of the lid.

Specifically:

*   **Box:** The box should have rounded corners, not just simple fillets. The base of the box needs to be slightly smaller than the top of the box and the walls need to be sloped slightly. I need to be able to set the inside dimensions of the box (inside length, inside width, and inside height) as parameters. Also, the wall thickness should be configurable. I think the easiest way to model the rounded corners is to use spheres in a hull. I'd like to have a little divot on the sides, which are just partial spheres, like on the existing design.

*   **Lid:** The lid should fit snugly onto the top of the box. It should overhang the box slightly and the top should be slightly smaller than the bottom. The lid should also have rounded corners that match the box. I need to be able to specify text to engrave on the lid. I'd also like to be able to set the size of the engraved text.

I'd like all of this to be in a parametric OpenSCAD file. So, I should be able to change all of these parameters in the customizer:
*   `inside_length`
*   `inside_width`
*   `inside_height`
*   `wall_thickness`
*   `lid_text`
*   `text_size`

The existing design also uses some scaling of the linear extrusion to create sloped walls. I think this is a good way to go, but we might consider using minkowski and scale for the main box body.

Also, it would be awesome if the design was easy to modify if I wanted to add some kind of latch mechanism later on. I'm using OpenSCAD 2021.01. I'm not sure if that matters. Thanks!

I need a set of OpenSCAD files to create a parametric battery adapter, specifically to adapt a smaller coin cell battery (like a CR2032) to fit into a device designed for a larger one (like a CR2450).  I want to be able to easily adjust all the critical dimensions in the OpenSCAD code.

Here's what I'm looking for in terms of parameters:

*   **Outer Battery Dimensions:** I need to be able to specify the diameter and thickness of the *larger* battery that the adapter will fit *into*. These should be `OUTER_BATTERY_DIA` and `OUTER_BATTERY_Z` respectively.
*   **Inner Battery Dimensions:**  Similarly, I need to specify the diameter and thickness of the *smaller* battery that will fit *inside* the adapter. These should be `INNER_BATTERY_DIA` and `INNER_BATTERY_Z`.
*  **Edge Contact Cutout:** There needs to be a cutout on the edge of the adapter to allow contact with the terminals. I need to set the width and height of this cutout, using the parameters `CONTACT_X` and `CONTACT_Y`.
*   **Inner Battery Protrusion:** I also need control over how much the inner battery protrudes towards the edge contact. This will be `CONTACT_PROTRUSION`.
*   **Printer Tolerance:** It would be great if I could specify a value `EXTRA` to account for how much extra material my printer tends to add to the model. This should adjust dimensions like radius and height of the adapter, by adding or removing from them according to the value of `EXTRA`.

I'd like the code to use differences to generate the shape by subtracting the inner battery volume and the contact cutout from a cylinder that would fit the outer battery. All dimensions are in millimeters. Also, I'd like the resolution of the curves to be controlled by a variable `$fn`, so I can adjust the print quality.  I plan on using this to print different adapters, so having all the parameters configurable in OpenSCAD is crucial.

I'm looking to create a parametric slot testing kit in OpenSCAD, similar to the one I've been playing with, but I'd like it to be more flexible and easier to customize.

Essentially, I need a design that includes two main parts: a "test block" with slots cut into it and a "tester block" with corresponding protrusions or "tabs" designed to fit into those slots.

Here's what I envision:

*   **Slot Shapes:** I want to be able to create three different kinds of slots: T-shaped, L-shaped, and rectangular. The default should be T-shaped, but I need to be able to switch easily. Each slot style should be controllable using the parameters I'm about to define.
*   **Test Block:** This will be a rectangular block with slots cut into three faces (left, right and back). All three slots should mirror each other in their style, dimensions, and filler usage.
    *   The main block should have parameters for `block_width`, `block_depth`, and `block_height`.
    *   There should be parameters for the slot dimensions: `slot_horizontal_width`, `slot_vertical_width`, `slot_height`, and `slot_midpoint_height`. The `slot_midpoint_height` will define the center vertical height of the slot.
*   **Tester Block:** This will also be a rectangular block, designed to fit into the test block.
    *  The tester block should have the same `block_width`, `block_depth`, and `block_height` as the test block but the block should be offset along the y-axis to allow a user to see how the pieces fit together. The user should be able to define an offset value: `tester_offset`.
    * The tester block should have protrusions that match the dimensions of the slots in the test block, plus some additional clearance/gap.
    *The tester block should also have parameters for clearance and gap: `slot_clearance`, and `slot_gap`.
*   **Fillers:** The slots should have optional "filler" pieces at the top and bottom of the vertical slot section. The amount of filler should be controlled by a percentage. This means the user will input a percentage (e.g. 50) and the filler will be the given percentage multiplied by the length of the horizontal and vertical slots.
    *   Each slot should be able to have a bottom filler and a top filler, so there should be four fill parameters: `slot_top_filler_percent`, `slot_bot_filler_percent`, `tester_top_filler_percent`, and `tester_bot_filler_percent`. The `slot_top_filler_percent` and `slot_bot_filler_percent` parameters will define the filler percentage for the test block slots and the `tester_top_filler_percent`, and `tester_bot_filler_percent` will define the filler percentage for the tester block tabs.
*   **Projections:** For convenience, I need the script to also generate "projection" pieces for both the slots and the tabs. These should be separate objects that can be extracted for use in other designs. This means that if the slot is changed to L-shape, the projection will also change to L-shape.
*   **Parametric Control:** I need all dimensions to be fully parametric, so they can easily be changed through variables at the top of the file.
*   **Libraries:** I'd prefer to keep this to base OpenSCAD as much as possible, but if you need to use libraries, please use BOSL2.

I think that about covers everything. Can you generate a parametric OpenSCAD file (or files) that satisfy these requirements?

[User] I need an OpenSCAD file that creates a sphere. I'd like to be able to control the sphere's size using a variable called "diameter", and I'd like to use a high resolution for it. Could you set the default diameter to 10 and use `$fn = 100`? I'd like the file to be named `sphere-diameter.scad`.

[Assistant]
sphere-diameter.scad:
```
diameter = 10;
sphere(d = diameter, $fn=100);
```


[User] I need a parametric OpenSCAD design for a cylinder. I want to be able to easily adjust both the radius and the height of the cylinder using variables. The cylinder should have a smooth, circular profile, so maybe use `$fn` for that? I'm thinking about making several different sizes for different projects, so a parametric approach would be ideal. I also need it all in a single `.scad` file. I'm not using any libraries, just standard OpenSCAD stuff.

[Assistant]
cylinder.scad:
```
height = 10;
radius = 5;
cylinder(h = height, r1 = radius, r2=radius, $fn=100);
```


[User]
I'd like to be able to create 3D printable cones with adjustable height and radius. I saw some example code that just used `cylinder` with `r2=0`, but I'd like something a little more robust. Could you generate an OpenSCAD file that lets me specify the height and radius as variables? It should generate a solid cone using the `cylinder` primitive, with fine control over the circular resolution using `$fn`, as in the example. I need to have a separate variable for the number of segments, instead of directly setting `$fn`.

Also, it'd be really helpful if the cone was centered on the origin in all axes.

[Assistant]
cone.scad:
```
height = 10;
radius = 5;
cylinder(h = height, r1 = radius, r2=0,  $fn=100);
```


[User] I'd like to create a square pyramid in OpenSCAD, but I want it to be fully parametric. I need to be able to specify both the base edge length and the overall height of the pyramid. Could you generate an OpenSCAD file for that? I'd also like it if the base were a perfect square; no distortions.

[Assistant]
square-pyramid.scad:
```
height = 10;
base_edge = 8;
cylinder(h = height, r1 = base_edge, r2=0,  $fn=4);
```
