I'm looking to design a parametric box that can hold embedded magnets. I've been looking around for something like this, and I think the best way to go about it is with OpenSCAD.

The box should have the following adjustable parameters:
*   **BoxOuterLength, BoxOuterWidth, BoxOuterHeight:** These define the external dimensions of the box.
*   **BoxWallThickness:** This is the thickness of the walls.
*   **BoxBaseThickness:** This is the thickness of the base of the box.
*   **MagnetDiameter:** The diameter of the magnets.
*   **MagnetThickness:** The thickness of the magnets.
*   **MagnetOffset:**  The distance from the corners at which the magnets are placed on each side.
*   **CylinderSideCount:**  How many sides to use when rendering cylinders for the magnet holes (if circular magnets).
*   **AirGap:**  The space between the magnet and the surrounding material, to allow a little wiggle room, and to allow space for bridging. This should apply to all sides of the magnet cutout.
*   **MagnetShape:** This should allow the user to choose either "circle" or "square" for the magnet shape. When "circle" is chosen, the top half of the magnet cutout (assuming proper orientation when printing) should render as a square so the magnets can be inserted mid-print.
*   **MagnetLocations:** This should allow the user to choose "bottom", "top", or "both" for where the magnets are placed. Top magnets should also be recessed by `BoxBaseThickness` to allow a roof to be printed.
*   **ShowCutawayView:** If set to true, this option should render a preview showing a cutaway to show half the magnet cutout depth, useful for debugging magnet placement.

The magnets should be placed on all four sides of the box, centered along each side's height.  They should be offset from the corners by `MagnetOffset`. If the magnets are on the top, they should be moved down by `BoxBaseThickness` to have a roof above the magnet.

I think that's everything.  Can you provide the OpenSCAD code for this?

I need a parametric OpenSCAD design for a 9-volt battery holder. I'd like it to hold multiple batteries, arranged in two columns. I'm imagining a box with a divider down the middle, so each column holds batteries stacked vertically.

Here are some details:

*   **Battery Dimensions:** A single 9V battery is approximately 17mm high, 26mm wide, and 48mm deep (including the terminals). However, the main body of the battery is only 44mm deep; the terminals stick out.
*   **Holder Structure:**
    *   The holder should have walls with a defined thickness.
    *   There will be a central divider separating the two columns.
    *   I want a cutout on the front of the holder so that the battery terminals are partially visible.
    *   I'd also like some kind of cutout near the bottom sides, to make the batteries easier to grab.
*   **Parameters:**
    *   `batteryHeight`: Height of a single 9V battery. (Default: 17mm)
    *   `batteryWidth`: Width of a single 9V battery. (Default: 26mm)
    *   `batteryDepth`: Depth of the main body of the battery, without terminals. (Default: 44mm)
    *   `anodeCathodeWidth`:  Width of the cutout at the front where terminals stick out. (Default: 22mm)
    *   `wallThickness`: Thickness of the holder's walls. (Default: 4mm)
    *  `tolerance`: A small amount to make sure the batteries fit, you might have to make this larger for your printer. (Default: 2mm)
    *   `batteriesInEachColumn`: Number of batteries in each vertical column. (Default: 4)
    *   `grabbingAreaDepth`: How far up from the bottom sides to add the grab-cutouts. (Default: 19mm)
*  **Labels:**
    *  I'd like "9 V" labels on the left, right, and centered. The centered label should be a "9" on top of a "V".
*   **Libraries:**
    *  I will be using the MCAD library, specifically boxes.scad.
    *   I will also need a text writing library with a `write()` function and the ability to load fonts like orbitron.dxf. I have one already from `Write.scad`, but I could also use BOSL2's text functions. I expect the final design to be written using your own text function.
    *  I have a utility library called `utils/build_plate.scad` that is used to draw the build plate, but this is not necessary for the core design.

I would like the design to be parametric, so I can adjust these parameters and make holders for different numbers of batteries or with thicker walls and such.

    When laying down with anonde/cathode along the x-axis and facing

I'd like to create a customizable display case for photos or lithophanes, similar to the one I found on Thingiverse (https://www.thingiverse.com/thing:5332102). It should be parametric, meaning I can adjust various dimensions and features.

Here's a breakdown of what I need:

**Core Structure:**

*   The case should be a multi-sided prism (like a hexagon, octagon, etc.). The number of sides should be adjustable.
*   Each side will hold an image/lithophane.
*   The design should have a base and a separate lid.

**Image/Lithophane Settings:**

*   I need to be able to set the width, height, and depth/thickness of the images.
*   There should be a border around each image.
*   There should also be a space between the image and the outside of the case.

**Size & Spacing Settings:**

*   I need to control the height of the base's bottom section and its walls.
*   Similarly, I need control over the lid's bottom section height and its walls.
*   I'd also like to be able to specify the size of the corners (though it notes it doesn't scale well yet, I might want to play with this).

**Preview Options:**

*   During design, I'd like to be able to toggle the lid on/off for previewing, and if on, lift it off the base.
*   I'd like a toggle to show preview cubes where the images will go.
*   A toggle for a preview circle inside to check light fitting compatibility would be nice, along with settings for the light's diameter and height.
*   It would be helpful to have an option for a build plate preview to make sure it'll fit in my printer. I need the length/height for this preview.
*   The ability to set colors for the base and "mid" sections would also be great for visual clarity during design.

**Output:**

*   The design should have the ability to export either the base or the lid separately.

**OpenSCAD Specifics:**

*   Please don't use any external libraries. Everything should be in one or more self-contained files.

I think that should cover everything. I'm looking for a flexible design that will allow me to easily adapt to different image sizes and numbers of sides. Thanks for your help!

Hey, I'm looking to create a customizable gyroscope fidget spinner with text on each ring, and maybe some images too. I've seen some examples that are close, but I'd like one I can really tweak.

Here's the idea:

*   **Gimbal Structure:** I need a series of concentric rings, and I want to control how many rings there are, their thickness, height, and spacing. I'd like to be able to set a largest diameter for the whole thing, and all the other dimensions should scale down from there.  The inner ring should be able to be optionally closed, and even optionally indented, if I wanted.

*   **Text:** Each ring should have the ability to have two separate text messages wrapped around them. I need to set the text, the font size, and the maximum letter spacing on the outside ring.  The letter spacing should also scale down as each ring gets smaller.

*   **Images:**  I would like to be able to load in a variety of images. Specifically:
    *   A dual SVG image, mirrored around the outer ring's text. I would like to be able to control the ratio of the image and where it starts.
    *   A single SVG icon to be placed somewhere on the outer ring.
    *   An SVG image that can be used to cut vertically through the center ring. I need to be able to resize the image and nudge its placement.
    *   Finally, top and bottom SVG images, with independent resize and nudge options.

*   **Rotation:** It would be cool to be able to rotate the gyro 90 degrees to change the axis of rotation of the middle section. Also, when that is done, I'd want the bottom image to rotate 180 to keep it correctly oriented.

*   **Visibility:**  I want to be able to toggle the visibility of the rings to see the text better.

*   **Resolution:**  I also want to set the resolution for the curvature.

I'd like this all in a parametric OpenSCAD file (or files). I'm not using any particular library, just whatever works best! I'd like to see some examples, as it would be a lot to specify all at once, but I'd really like all of the above to be included in the final script.

Okay, I'd like to get a parametric OpenSCAD design for a box that I can 3D print in vase mode, also known as spiral mode. It should let me specify the width, depth, and height of the box. I'd like to have the option to round the corners or keep them sharp. So, there should be a boolean variable for that called something like `rounded_corners`, with true or false values. I don't need a top, the box should be open. I don't need the walls to have a thickness variable since vase mode has specific parameters on my slicer for that already.

Also, I'm not sure if this is needed, but I'd like it if there was a minimum size for the width and depth to be at least 15mm, so that the box doesn't become too small. This part should be done in the code itself not just when I'm entering values.

No special libraries or dependencies are needed. It will just use the OpenSCAD core functionality.

I'm looking to design a seed starter tray system for compressed peat pellets, like the Jiffy brand ones, and I need help generating the OpenSCAD code for it. I want it to be customizable in terms of the number of rows and columns of pellets it can hold, as well as the pellet dimensions and the height of the lid.

The system will consist of three main parts: an "Upper" tray which holds the pellets, a lid, and a drip tray. I want to be able to render these individually or all together.

Here's a breakdown of the requirements for each part:

**Upper Tray:**
*   This is the main part and should hold the peat pellets. It needs to be solid, so it should be printed with enough walls to be waterproof.
*   The dimensions for pellet size (diameter and height) should be customizable.
*   The tray should have a floor.
*   The wall thickness for the pellet holes and the floor thickness should be configurable parameters.

**Lid:**
*   The lid should fit snugly on top of the Upper tray.
*   It should have a thin wall and top. I plan to print this upside down with a single bottom layer, no top layers, and low infill (5-10%).
*   I also want a parameter to control the lid's height and the thickness of the lid's wall and roof.
*   I'd like to include an option for adding vent holes to the lid (this should be configurable with a boolean).

**Drip Tray:**
*   This tray sits under the Upper tray to catch drips.
*   It should have slats for airflow.
*   It needs a floor and walls, as well as parameters to control its floor thickness, the depth, and a margin around the Upper tray.

I want these parameters to be customizable:
*   `ROWS`: Number of rows of pellets.
*   `COLS`: Number of columns of pellets.
*   `PART`:  A string that specifies which part to render ("ALL", "UPPER", "LID", "TRAY").
*   `AIR_VENT`: A boolean to control the presence of vent holes on the lid.
*   `PELLET_D`: Diameter of a pellet.
*   `PELLET_H`: Height of a pellet.
*    `LID_H`: Height of the lid.
*   `FLOOR`: Thickness of the floor for the Upper tray.
*   `WALL`: Thickness of the wall for the Upper tray and the base of the lid.
*   `LID_WALL`: Thickness of the lid's wall.
*   `LID_FLOOR`: Thickness of the lid's roof (printed as the bottom).
*  `TRAY_FLOOR`: Thickness of the drip tray's floor.
*   `TRAY_DEPTH`: Depth of the drip tray.
*    `TRAY_MARGIN`: Margin around the upper tray for the drip tray.

I'd like to include `minkowski` to ensure that all of the wall thickness is uniform, and to make it easy to create smooth fillets and rounded corners. If `hull` is suitable for some elements, that can be used as well.  I'm not trying to reduce the polygon count by using `polygon`, since I need even thickness in the walls, but if `polygon` or any other more complex operation is better for the vents, it could also be considered.

Let me know if you need any other info. Thanks.

This is a tray with lid for compressed peat seed planters, including Jiffy brand ones.
I've designed it to be highly customizable.abs

The main part is the "Upper"
I suggest printing it solid to avoid leaks. I also used a slightly higher than normal temperature.

The Lid is what is says on the label.
It's designed to print with 1 layer thick walls.
I suggest printing it upside down with 1 lower layer and 0 upper layers, 5-10% infill.
This will generate a lid that is thin, but with a few infill traces to help it hold together better. If your first layer is perfect you could also use zero infill or adjust the settings for a thin top.abs

The Tray is just a drip tray, with slats to allow for airflow.
It's probably not needed, but can help if your original print isn't quite 100% watertight or you drip while watering.

I need a customizable hex key designed to fit the gear bearing on thingiverse by emmett (thing:53451). The key should have a hexagonal shaft and a thumb grip.

The shaft should be a hexagon with a diameter that I can adjust, defaulting to 7.1mm to match the gear bearing. The length of the shaft should be adjustable too, defaulting to 120mm, with the thumb grip taking up a portion of that length. The thumb grip itself should be a cuboid, with a length of 25mm. It should be centered on the end of the shaft, meaning that only half of the thumb grip's length is added to the overall length of the key. I'd also like to adjust the width of the thumb grip. The default should be 25mm for both width and height, forming a cube shape.

I'd like to be able to adjust all of these dimensions:
*   `hex_diameter` (default 7.1mm)
*   `total_length` (default 120mm)
*   `thumb_side` (default 25mm)

I'm expecting a single .scad file.

Hey, I'm looking for an OpenSCAD design for a customizable bunny-shaped Easter egg holder. I want it to be parametric, so I can easily adjust the size and shape to fit different eggs and preferences. I'm looking to print both the bunny holder and also be able to print eggs if necessary.

Here are the parameters I'd like to control, basically mimicking the existing design I found (I'll include the comments from that design too):

**General**
*   `Part` - A way to choose whether to generate just the bunny holder, an egg shape, or both for preview.
*   `Material_Thickness` - The thickness of the material used for the bunny.
*   `Rounding` - The amount of rounding on the edges of the bunny.

**Bunny - Egg Hole**
*   `Egg_Hole_Height` - The height of the hole that will hold the egg.
*   `Egg_Hole_Width` - The width of the egg hole.

**Bunny - Ears**
*   `Ears_Width` - The width of the ears.
*   `Ears_Height` - The height of the ears.
*   `Ears_Placement_Percent` - The vertical placement of the ears as a percentage of the head's height.

**Bunny - Left Ear**
*   `Left_Ear_Head_Angle` - The angle of the left ear relative to the head.
*   `Left_Ear_Rotate_Angle` - How much to rotate the left ear from its base.
*   `Left_Ear_Bend_Angle` - A bending angle for the left ear.

**Bunny - Right Ear**
*   `Right_Ear_Head_Angle` - The angle of the right ear relative to the head.
*  `Right_Ear_Rotate_Angle` - How much to rotate the right ear from its base.
*   `Right_Ear_Bend_Angle` - A bending angle for the right ear.

**Bunny - Head**
*   `Head_Diameter` - The diameter of the bunny's head.
*   `Head_Placement_Percent` - The vertical placement of the head as a percentage of the height of the body.

**Bunny - Body**
*   `Body_Shape` - Option to use an offset egg shape, scaled egg shape or an oval shape for the bunny's body.
*  `Body_Thickness` - How thick the material will be around the hole for the egg.

**Bunny - Feet**
*   `Foot_Height` - The height of the feet.
*   `Foot_Length` - The length of the feet.
*   `Foot_Gap` - The gap between the feet.

**Egg**
*   `Egg_Type` - Option for round or flat egg.
*   `Egg_Orientation` - Option to orient the egg upright or on its side.
*   `Egg_Height` - The height of the egg.
*   `Egg_Width` - The width of the egg.

I'd like the design to use a custom function for the egg shape profile, like the one included in the code I saw, specifically: `// x^2 = 3 * sqrt(2y + 1) - 2y - 3`.

I think that covers everything.  I'm not sure if it needs any additional libraries, but if you think so, please let me know.

Hey, I'm looking to get a custom lockbox designed for 3D printing. I have a basic idea, but I'd love it if you could generate the OpenSCAD files for me. I've included the original SCAD file for reference.

The lockbox should have two main parts: the box itself and a lid.

For the box, I need to be able to specify the inside width, height, and depth as parameters. I also need to be able to control the wall thickness. The lid should fit on top of the box, and the lid should have a lip that fits inside the box opening. I need to be able to set parameters for the lid thickness, the lip height, the lip thickness, and the diameter of the hole for the padlock. I need to have the hole positioned along the lid's mid-length. I also want a bit of extra space around the hole and a small tolerance between the lid and the box for easier assembly.

I would like the box to be printed with a base, lower walls, a section for the lid to rest on, and then top. The lid should have a lip and base.

I'd like to be able to easily specify these parameters and see the results in OpenSCAD. I'm not looking to include any libraries or additional dependencies at the moment. Ideally, the preview will show both the lid and the box together, but I'd also like to be able to export the box and the lid as separate parts.

I'd like to be able to set:
*   `x` for inside box width
*   `y` for inside box height
*  `z` for inside box depth
*   `walls` for wall thickness
*   `tolerance` for the gap between the box and the lid
*   `hole_diameter` for the padlock hole
*   `lid_thickness` for the lid thickness
*   `lid_lip_height` for the lip height
*   `lid_lip_thickness` for the lip thickness
*   `hole_extra` for extra space around the hole
* `distance` for space between hole and box

I'd also like an export setting for 'part' that can be set to "box", "lid", or "both", just like in the example. The 'both' setting should be the default. Thanks a lot!

Hey there, I'm looking to get a custom design for a divider for my car's cupholder. I've got a VW ID.4, and I'd like a divider with a few coin slots built in. I'm imagining something similar to the included ID4_Console_Dividers_V0_2.scad file, but with a few tweaks, and I'd like it to be parametric so I can easily customize it myself.

First, the basic divider part: I want to be able to set the overall width, height, and thickness of the main body. There should also be slots on each side of the divider that will grip into the cupholder, and I'd like to be able to adjust their width, height, and depth. It should also be possible to adjust the diameter of the gripping circles, and how far up the slots these circles are positioned on the slot. Finally, I want to control the chamfer that's on the bottom of the divider, and the little detent cutouts on the side of the slots.

For the coin slots: I need to be able to specify how many coin slots there are. Then, for each slot, I need to specify the width of the slot, the thickness of the coin it's meant to hold, and how deep I want the slot to be. There should also be a small separator width between the coin slots, a small width of material at the top of the slot, and a small thickness of material holding the coins. Finally, there should be a ramp at the bottom of the slot. It should be possible to customize the height of the ramp.

So basically I want a parametric divider with slots to hold my coins. I'd like you to generate the necessary OpenSCAD files. I don't need any extra libraries for now, just the main file.

I'd like to design a watering can nozzle in OpenSCAD. I have a basic idea of the design, but need some help generating the code. It needs to be parametric so I can easily adjust the size and number of holes, and also fit it to my specific watering can.

The nozzle has a cylindrical main body with a wider, flared outlet end, and a smaller cylindrical connector on the opposite end to fit onto the watering can spout. I'm thinking that the connector should have a slightly larger inner diameter than the outer diameter of my watering can's spout so that it can fit snuggly. I'll need to account for the wall thickness of the nozzle itself too.

Specifically, the following parameters are going to be important to control:

*   `connector_inner_diameter`: The inner diameter of the connector, should be slightly larger than my watering can's spout.
*   `nozzle_diameter`: The diameter of the wide, flared outlet end of the nozzle.
*   `nozzle_height`: The height of the flared main body.
*  `connector_height`: The height of the connector part.
*   `wall_thickness`: The thickness of the nozzle walls.
*   `hole_diameter`: The diameter of the individual water outlet holes.
*   `hole_diameteristance`: The tangential distance between the holes.
*   `hole_radius_distance`: The radial distance between the rows of holes.

The design will be a hollow shape, so it will be a difference between a solid and an internal solid. The holes should be generated in a circular pattern across the flared part. I will need to make sure to calculate the area to keep the flow rate correct.

I don't need any special libraries like MCAD, I think it can be achieved with the standard features of OpenSCAD.

Could you generate the OpenSCAD file for this design based on these parameters?

I'd like to design a storage cover for a sugar thermometer, something that will protect it when it's in a drawer. I've got some basic dimensions I'm working with, and I'd like to make it parametric, so I can adjust things later.

Essentially, it's a long rectangular box with a slot cut out for the thermometer, and a small tongue that extends past the main body to cover the pan holder part of the thermometer. I want to add some small tabs to the long sides to help with gripping the cover, and optionally some stiffening rails on the bottom.

Here are the core dimensions:
*   `length`: the overall length of the cover
*   `width_inside`: the interior width for the thermometer
*   `height_inside`: the interior height for the thermometer
*   `thickness`: the thickness of the walls
*   `tongue_length`: how long the tongue sticks out past the main body
*   `tongue_width`: the width of the tongue
*   `tabs`: how far apart the tabs are, or rather, the length of the side without tabs
*   `lip`: how far the tabs stick out on the sides (not depth, rather thickness)
*    `rails`: 0 or 1 for whether or not to add stiffening rails
*   `rail_width`: width of the rail
*   `rail_height`: height of the rail

I'd like the cover to be centered on the origin. Also, could you add variables for the outside dimensions, and for the midpoint of the tongue? I'm not sure where the tongue midpoint should go right now, but it will be useful to have it in my mind as I tweak things.

I think that's it for now. Can you generate the OpenSCAD file(s) for that? I'm not using any libraries for this one.

Okay, I'd like to design a parametric chisel holder for a Tormek sharpening system. I'm thinking of a design similar to the one I've seen, where the chisel is held *below* the bar, allowing for very short chisels to be sharpened at steep angles. It uses a carriage bolt and a pronged t-nut for clamping.

Here are the key features and dimensions I have in mind.  The design will require `MyStuff2.scad` and `MyStuff.scad` for some helper functions (I think, mostly `fn()`).

**Overall Design:**

*   The main structure is a clamp block that holds the chisel. There will be mirrored left and right versions.
*   The clamp block slides along the Tormek bar using a hole that's slightly larger than the bar's diameter. It clamps onto the bar using a carriage bolt and knob.
*   The chisel sits on a ledge, and is held in place with pressure from the carriage bolt, and a pivoting arm.
*   The bolt head and a t-nut are housed within a knob that gets screwed onto the carriage bolt.
*   There's a threaded insert on each side that interfaces with the bolt and sits in the pivot arm.

**Key Parameters:**

*   `BarDiameter`: Diameter of the Tormek bar the holder slides on. (Default: 12.1 mm)
*   `Material`: Thickness of the material around the bar hole. (Default: 3.5 mm)
*   `SleeveLength`: Length of the holder along the bar. (Default: 20 mm)
*   `Epsilon`: A small value for making sure parts fit. (Default: 0.01)

**Threaded Insert Parameters:**
* `ThreadInsertHeight`: Height of the threaded insert portion. (Default: SleeveLength)
* `ThreadInsertDiameter`: Diameter of the threaded insert. (Default: 7.7 mm)
* `InsertSpikeDiameter`: Diameter of the insert spike portion (that is, the part that doesn't have a thread). (Default: 19 mm)
* `InsertSpikeHeight`: Height of the insert spike (that is, the part that doesn't have a thread). (Default: 6.5 mm)
* `InsertSpikeWidth`: Width of the slots in the insert spike. (Default: 3 mm)
* `InsertSpikeThickness`: Thickness of the slots in the insert spike (Default: 1.5 mm)

**Bolt and Knob Parameters:**

*   `BoltHeadDiameter`: Diameter of the carriage bolt head. (Default: 15 mm)
*   `BoltCarrageDimension`: Dimension of the square carriage part below the bolt head. (Default: 7 mm)
*   `BoltHeadHeight`: Height of the carriage bolt head. (Default: 3.5 mm)
*   `BoltThreadDiameter`: Diameter of the bolt thread. (Default: 6.2 mm)
*   `KnobHeight`: Total height of the bolt knob. (Default: 20 mm)

**Clamp Block Specifics:**
*The clamp will have a pivoting arm for applying pressure to the chisel.
*   The arm will pivot around the `InsertSpikeDiameter`
*   The clamping face should be about 6mm in height, and have a flat at the clamping point
*   The chisel rests on a ledge that's slightly under the bar diameter.
*   The holder will also need to be slightly wider than the bar's diameter to clamp correctly.

**Module Breakdown:**

I was thinking of something like this:

*   `ClampBlock(Insert)`: Creates the main clamp block. It is mirrored and can have a threaded insert for the bolt. It calls other modules.
*   `CarrageBoltHolder()`: Creates the knob that holds the bolt.
*   `BarHolder(Length,Insert)`: Creates the part that clamps the bar.
*   `ThreadInsert(Subtract)`: Creates the threaded insert to hold the carriage bolt.
*   `SpikeSlot()`: Creates one of the slots within the thread insert
*  `Test()`: A simple test cylinder to show ID/OD with correct allowances for the bar.

**Functionality:**

*   The design should be parametric, allowing for different bar diameters, bolt sizes, material thicknesses, and other dimensions.
*   I'd like to be able to select specific parts to render (e.g., left clamp, right clamp, knob) or render everything together.
*   The "clamp block" (or pivot arm) should create pressure on the chisel in a linear or arc'd motion.

Could you generate the OpenSCAD code for this? I'm happy to provide more details if needed.

Hey there, I'm looking to get a custom funnel designed in OpenSCAD. I really like the idea behind the `FunnelPrim.scad` file I saw, but I need something a bit more flexible, and I'd like to be able to adjust a few parameters that aren't exposed in that design.

Specifically, I need a funnel that fits over various cylindrical objects, not just moka pots and canning jars. I want to be able to control the following:

1.  **Base Diameter:** The inner diameter of the base of the funnel, which sits over the cylindrical object.
2.  **Base Height:** The height of the cylindrical part of the funnel.
3.  **Base Lip Height:** The height of any lip or overhang at the base, designed to sit on the object's lip or edge.
4.  **Funnel Angle:** The angle of the funnel itself.
5.  **Funnel Height:** The height of the angled part of the funnel.
6.  **Wall Thickness:** The thickness of the funnel walls.
7. **Clearance:** I'd like to be able to set the clearance between the inner diameter of the funnel base and the outer diameter of the target object.

I want to be able to specify these dimensions directly, rather than choosing from a limited set of predefined sizes. I'd also like to be able to generate either a profile view of the funnel (like the existing `profile()` module) or a 3D model as needed.

The `FunnelPrim.scad` uses `rotate_extrude` and a `polygon` definition to define the funnel shape. I think that's a good approach, so it would be great if you could use that same approach with these user-definable parameters. The existing code also has a variable to control `$fn`, and I'd like to keep that customizable as well.

I'm thinking this will need to use the standard OpenSCAD libraries. I'm not looking for any specialized ones like MCAD or BOSL here. I'd like for the default to output a 3D model with the specified parameters, but it should also be possible to output the profile view as well.

Could you please provide me with a parameterized OpenSCAD file, or set of files, that meets these needs? Thanks!
