Okay, I'd like to design a linked bracelet using OpenSCAD, but I want it to be highly customizable. The design I have in mind is based on a "figure-8" style link, where the links interlock and repeat around the circumference of the bracelet.

Here are the specific parameters I need to be able to control:

*   **`link_diameter`**: This should control the overall size of each individual link, essentially the "thickness" of the bracelet. I'd like to specify this in millimeters.  I'm thinking a range of about 14mm to 32mm should be good.

*   **`bracelet_diameter`**: This determines the overall diameter of the bracelet itself, in millimeters. I'd need to be able to adjust this to fit different wrist sizes, so a range from 30mm to 300mm sounds reasonable.

*   **`extruder_colour`**: I'm planning to print this on a dual extruder printer, so I need an option to choose which "color" to output. The options would be "Colour1", "Colour2", or "BothColours" where the links alternate colors. I expect the two colors would be incorporated into two interlocking link structures, and then a hull to connect them.

The links themselves should have a slightly rounded, octagonal tube cross-section, not just a simple circle. The original code uses a Minkowski sum of an octagonal tube and a diamond to achieve this. The links interlock as in the provided code, rotating a standard module around the circumference of the bracelet.

I'd like the code to calculate the number of links required based on the `bracelet_diameter` so the links interlock properly. I don't need to specify the number of links directly.

The design should be able to be generated without any additional files or dependencies beyond standard OpenSCAD capabilities.

I think that covers everything. Can you generate an OpenSCAD file that meets these requirements?

Okay, I'm looking to create a customizable pill organizer using OpenSCAD, and I've seen some designs that seem close, but I want something more tailored to my needs. I'd like to be able to specify the number of days, weeks, and whether the lid has text on it.

Here's what I'm thinking:

**Core Structure:**

*   **Individual Pill Compartment:** Each compartment should be a small rectangular box with a slightly recessed interior, basically a cube with a smaller cube cut out.  It needs a small clasping mechanism on the top face, that will allow for the lid to be attached. Two clasps per pillbox should do it.
*   **Day Modules:**  A collection of these individual compartments should be combined into "day modules" arranged horizontally, this makes the pillbox easy to understand and use. The number of compartments per day should be user defined, for some people they may take 7 pills a day, others might only take one.

*   **Week Modules:** These day modules will be further arranged to represent the weeks, each week module being placed horizontally from the previous one. The number of week modules should be customizable as well.
*   **Lid:** The lid will consist of a rectangular piece that mirrors the base and has small tabs that can slot into the clasps on the box and hold the lid firmly in place.

**Customization Requirements:**

1.  **Number of Days:** I want to be able to specify the number of days (and thus, the number of pill compartments in a row) to include in each "week" of the pillbox. This could be anywhere from 1 to 7, or perhaps even more in the future.
2.  **Extra Compartment:**  I'd like to have an optional "extra" compartment at the end of each "day row". This would be useful for things like PRN medications or supplements.
3.  **Number of Weeks:** I need to be able to choose how many week rows to include. This could range from 1 to 4 or even more, allowing me to prepare pills for a full month.
4.  **Text on Lid:** I'd like an option to add text to the lids of each week section. If the user does not select this option, then no text should be included. The text should be the letters of the week if there are 7 days, or numbers for less, plus the letter E at the end for the extra compartment, if it exists. I'd also like this text in Braille below each section of text, using a braille font.
    *   The text should be placed on the lid of the "week module", oriented so that when the lid is placed on the pillbox it is correctly oriented.
    *   I'd prefer the standard letters to be large and clear, and the braille to be smaller but still legible.

**Other Requirements/Notes:**

*   I'm not familiar with all the libraries, but I'm using the `Write.scad` library for text rendering.
*   I'd like the compartments to have a reasonable size - say, 20mm x 20mm x 20mm with 18x18x18 inner, and the clasps 1x5x1.
*   I'd like the lid to have tabs that are slightly recessed, to keep the lid firmly in place, with the dimensions being 1x5x1, and recessed by .1.
*   The spacing between individual compartments within a day row should be consistent and, say, 19mm.
*   I'd like to ensure the braille text is well-spaced so the dots don't overlap.
*   The overall design needs to be parametric so that I can easily adjust all of these values.
*   I'm expecting the OpenSCAD to generate a solid 3D printable object.

Could you help me generate an OpenSCAD script that meets these specifications? Let me know if you have any questions.

Okay, I'm looking to create a customizable pill organizer using OpenSCAD. I'd like the design to be parametric so I can easily adjust the number of compartments, their size, and the overall dimensions of the box.

Here are the specific things I need:

*   **Compartments:**
    *   I need to be able to specify the length, width, and height of each individual compartment.
    *   The compartments should be arranged in a grid.
    *   I need to specify the number of days (rows) and the number of doses per day (columns). For example, I might want a 7 day organizer, with 3 doses per day.
    *   There needs to be an option for the walls of each compartment to be a consistent thickness. This thickness can be hardcoded, as it won't be varied by me.

*   **Labels:**
    *   I want to include text labels above each column to designate the time of day (e.g., "B", "L", "D" for Breakfast, Lunch, and Dinner, for example).
    *   These labels need to be customizable. I should be able to specify the text for each column. I expect these labels to be relatively short, probably one or two letters each.

*   **Nubs:**
    *   I need an option to add small nubs, or pegs, to the bottom of the pill organizer. I will use this to align a lid (though the lid design isn't part of this request).
    *   There should be an option to turn these nubs on or off.

*   **Overall:**
    *   I need to be able to specify the total height of the box.
    *   I need to specify whether I am printing a lid or not, as this will determine the inclusion of the nubs.
    *   I'm using the `write.scad` library to generate the text for the labels, specifically the `write()` module.

I think that covers everything. Could you provide me with an OpenSCAD file that does all of that?

[User]
Okay, I'd like to design a custom vase using OpenSCAD, and I'd like it to be parametric so I can easily tweak it later. I have a good idea of the features and parameters I want.

Here's what I'm looking for:

**Overall Shape and Style:**
*   The vase should be based on a sphere, but it will be modified by cutting away parts using vertical loops or embossed patterns.
*   I want to select from several pre-defined styles:
    *   Plain: Just a simple sphere with top and bottom cutouts, and optional rings.
    *   Single Loops: The sphere should have vertical holes cut all the way through, creating "loops."
    *   Double Loops: The sphere should have two sets of overlapping vertical loops.
    *   Triple Loops: The sphere should have three sets of overlapping vertical loops.
    *   Single Emboss: The sphere will have a partial vertical cut, but not all the way through, creating an "embossed" pattern
    *   Double Emboss: Two layers of embossing, the second slightly offset.
    *   Triple Emboss: Three layers of embossing, the second and third slightly offset.
*   I also want a line style to control the angle of the loops/emboss; either angled outward or inward (though apparently angled inward isn't working correctly).

**Dimensions and Ratios:**
*   **Vase Width:** I need to be able to set the overall width of the vase in millimeters. All other dimensions will derive from this.
*   **Vase Depth Ratio:** A ratio to control how deep the vase will be, relative to the width, to allow it to be wide or narrow.
*   **Vase Height Ratio:** A ratio to control the height of the vase, relative to the width, to make it short or tall.
*   **Vase Wall Thickness:** I need to control the thickness of the vase wall in millimeters (e.g., 1mm thin, 2mm normal, etc.).
*   **Top Hole Opening Ratio:**  A ratio that sets how wide the hole at the top will be, compared to the vase width.
*   **Bottom Base Ratio:** A ratio that sets how wide the base at the bottom will be, compared to the vase width.
*   **Basic Shapes:** A control for changing the shape of the hole. I'd like to choose between circular holes and more complex shapes like diamonds or emeralds. This affects the cross-section of the 'loops' and the embossed areas.
*   **Ring and Base Ratio:** A ratio to make the rings at the top and base thicker or thinner compared to the vase wall.
*   **Include Ring at Top:** A boolean to optionally include a decorative ring at the top.

**Loop Settings (for loop styles):**
*   **Number of Loops:** An integer setting the number of loops going around the vase.
*  **Loop Width:** A ratio to set the width of each loop.
*   **Loop Overlap:** A ratio controlling the vertical overlap between loops in double and triple loop styles.
*   **Loop Angle Offset:** A ratio allowing me to stagger the vertical position of the loops.
*   **Middle Loop Ratio (for triple loops):** A ratio setting the relative size of the middle loop in a triple loop design.
*   **Skip Loops:** A boolean to skip every other loop for certain styles.

**Emboss Settings (for embossed styles):**
*   **Emboss Percentage:** The percentage of the vase wall that is filled with the embossing.
*   **Emboss Angle:** The angle at which the embossing is tilted (this can create angled or even looping emboss patterns)

**Additional Features:**

*   I'd like to use the `build_plate.scad` library to show the build plate in the preview. The build plate should be configurable for Replicator 2, Replicator, Thingomatic, or manual dimensions.

**Specific Parameters for Initial Design:**
For the initial design, please use the following values:
*   Vase Style: Triple Emboss (6)
*   Line Style: Angled Out (1)
*   Vase Width: 60mm
*   Vase Depth Ratio: 0.7
*   Vase Height Ratio: 1.2
*   Vase Wall Thickness: 2mm
*   Top Hole Opening Ratio: 0.5
*   Bottom Base Ratio: 0.2
*   Basic Shapes: Ovals (50)
*   Ring and Base Ratio: 1
*   Include Ring at Top: Yes (1)
*   Number of Loops: 9
*   Loop Width: 0.5
*   Loop Overlap: 0.375
*   Loop Angle Offset: 0.25
*   Middle Loop Ratio: 3
*   Skip Loops: No (0)
*   Emboss Percentage: 0.3
*   Emboss Angle: 30
*   Build plate: Replicator 2 (0)

I'm excited to see what you come up with! I think this will make some very unique vases. Thanks!

Okay, so I'm trying to create a lid for a customizable pill box I found online, and I need help generating the OpenSCAD code. The pill box itself is made up of individual compartments arranged in a grid, and the lid needs to fit snugly over the entire thing.

Here's how the pill box is structured:

*   **Compartment Dimensions:** Each individual compartment has a length and a width, which I can adjust. These are specified as `Length_For_Each_Compartment` and `Width_For_Each_Compartment` respectively. I can change them, but in the example code, the defaults are 20 and 35.
*   **Overall Height:** The height of the entire lid is specified by `Height_For_Entire_Model` and in the example is 15.
*   **Grid Arrangement:** The compartments are arranged in a grid. I can specify the number of days (i.e., the number of rows), `number_days`, and the number of compartments per day (i.e., the number of columns), `number_per_day`. The example uses 7 days and 3 compartments per day.

The OpenSCAD code I started (which I'll provide below) uses subtraction to cut out the interior of the lid, leaving a thin shell. The lid sits over the container itself and would be slightly larger than the box so that the two fit together. This difference is specified as 4mm in both the X and Y dimensions.

I'm using text for each row that will be embossed on the side of the lid. I have variables to do this: `row_one`, `row_two`, `row_three`, `row_four`, `row_five`, and `row_six`, and these will correspond to one letter for each row. I would like the program to accommodate the correct number of rows automatically using only the variables `number_days` and the strings. So, if I only specify 3 days, I would expect only 3 rows, etc.

I'd also like to include an option for small nubs on the bottom of the lid that correspond to the number of compartments per day (so 3 nubs if there are 3 compartments per day). I have a parameter for this, `nubs`, which I would like to handle with a 0 (yes) and 1 (no). This feature is not included in the code I started.

Could you generate the OpenSCAD code for this lid, incorporating these parameters and the text and nub options? Specifically, the lid should have the same height as specified by `Height_For_Entire_Model` and extend slightly past the main pill box body as specified. I am not using any special libraries at this time, but I am not opposed to incorporating one, should you think it necessary.

I'm also including the code I have to show how I was doing the subtraction before:

Okay, I'm looking for help designing a device for ice fishing, something that will alert me when a tip-up flag goes off. I've got a basic design in mind, but I need it to be parametric in OpenSCAD so I can easily adjust it for different components and tip-up sizes.

Here's the basic idea: It's a small enclosure that attaches to the tip-up's rod. Inside the enclosure, there's a buzzer, an LED, an on/off switch, a tilt switch (mercury switch), a resistor, and a battery. When the tip-up flag is triggered, the device tilts, activating the tilt switch, which then triggers the buzzer and LED. It needs to be loud enough to hear during the day and bright enough to see at night.

Here are the specific components I'm working with, with some dimensions:

**Buzzer:**
*   Diameter: 17.5mm
*   Lip Diameter: 14.5mm
*   Lip Length: 2mm
*   Total Length (including lip): 14.5mm
*   Retainer Diameter: 13.5mm
*   Retainer Length: 10mm

**LED:**
*   Diameter: 5.75mm
*   Lip Diameter: 7.5mm
*   Lip Thickness: 1.4mm
*   Hole Length (depth for LED): 1.5mm
*   Retainer Length: 2.0mm

**Resistor (1/4W):**
*   Diameter: 3.5mm
*   Length: 15mm

**Tilt Switch:**
*   Diameter: 6mm
*   Length: 24mm

**On/Off Switch:**
*   Dimensions (body): 6mm x 12mm x 8mm
*   Switch Dimensions (the moving part): 3mm x 6mm x 1.0mm
*   Retainer Dimensions: 6mm x 8mm x 2mm
*   Flange Dimensions: 5mm x 20mm x 1mm

**Battery (A23):**
*   Diameter: 10.35mm
*   Length: 27mm + 1mm (variance) + 2mm (spring) = 30mm total
*   Positive Terminal Diameter: 5.5mm
*   Positive Terminal Length: 1mm
*   Positive Terminal Base Diameter: 8.25mm
*   Positive Terminal Base Thickness: 3.25mm
*   Spring Retainer Length: 6mm
*   Spring Retainer Diameter: 6mm

I need the OpenSCAD design to include:

*   **Enclosure:** A box that holds all these components. The dimensions should be derived from the components themselves, with a small border around them, maybe 1mm. It needs to have two parts, a left side and a right side that fit together.
*  **Rod Attachment:**  A part to attach the enclosure to the fishing rod, using cable ties (zip ties). The rod diameter needs to be parametric, as does the cable tie width and height.
*   **Retainer Clips:** Clips to hold the left and right enclosure parts together
*  **Channels for wiring:**  A means of routing the wiring between components inside the enclosure.
*   **Parametric dimensions:**  All dimensions of the components, enclosure, cable tie slot, and rod attachment need to be parametric and easily adjustable.
*   **Preview Option:**  I'd like a way to select different "parts" to display. Options would be the assembled device, just the left side of the enclosure, just the right side of the enclosure, just the rod attachment, and just the retainer clips. A preview view of the assembled device will be useful too.

I'd like the code to make use of the `utils/build_plate.scad` library to display a visual build plate for size reference. I'd like to have the option to select some pre-defined build plates or input them manually.

Finally, I'd like the final design to be centered in the OpenSCAD platform, and able to show a preview using a south facing view with a top diagonal tilt. I'd also like for the model to be easily exported for 3D printing.

Can you generate the OpenSCAD code for this?

Okay, I'd like to design a 3D printable vase based on the spirograph principle, but I want a lot more control and flexibility than what the example code provides.

I'm looking for a parametric OpenSCAD file that allows me to create a variety of spirograph vases. The basic principle should still be there: a rotating circle (or cog) moving around a fixed circle (or cog), with a 'pen' at a certain distance tracing the design. The design will be then extruded to create a vase with an optional twist, plus a base.

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

*   **Spirograph Type:** A boolean or enum to choose between hypotrochoid (rotating inside) and epitrochoid (rotating outside). The current code uses `isHypotrochoid = 1;`, but a more descriptive name or enum would be useful.
*   **Fixed Radius (R1):** The radius of the fixed circle.
*   **Rotating Radius (R2):** The radius of the rotating circle.
*   **Pen Distance (D):** The distance of the "pen" from the center of the rotating circle.
*   **Number of Rotations (turns):**  How many times the rotating circle completes a revolution around the fixed circle. This is important for complex patterns. The current code uses `turns`, which is good.
*   **Wall Width:** Thickness of the vase walls.
*   **Number of Segments (N):**  The number of line segments used to approximate the spirograph curve. The example code uses `Segments`.
*   **Twist Cycles:** How many cycles of twist are applied over the height. The example uses `twistCycles`.
*   **Vase Height:** The overall height of the vase. The example uses `height`.
*  **Layer Height**: The vertical layer thickness for linear extrusion. The example uses `layerHeight`.
*   **Base Thickness:** The thickness of the base.
*   **Base Shape:** The base is currently a cylinder, but I'd like to be able to change this:
    *   **Option 1: None:** No base at all.
    *   **Option 2: Cylinder:** Like the current code, a simple cylinder.
	*   **Option 3: Spirograph Extrusion:** Instead of a cylinder, the base is a flat, un-twisted extrusion of the spirograph itself, with its shape matching the bottom of the vase.
*   **Top Type:** I need the ability to control the top.
    *   **Option 1: Flat:** The current vase has a flat top.
	*   **Option 2: Closed Top:** I want the option to close the top with a flat surface that matches the top of the vase.
*   **Smoothing:** Add optional smoothing or interpolation to the spirograph curve using Bezier curves or similar to get smoother contours. This could use a smoothing factor. This is important for larger values of N, where the segmentation lines might be too obvious.
*   **Customizable Extrusion Profile:** Rather than a simple `linear_extrude` with a circular cross-section, I would like to be able to define an extrusion profile, such as a rectangle, ellipse, or even a custom shape using a 2D polygon. This will allow for different visual effects for the wall, such as thicker or thinner sections, or a decorative profile. The current code uses `wallWidth` which is essentially a diameter and the extrusion uses a circle, so this requires more flexibility.
*   **Preview mode:** I would like to generate a 2d preview of the spirograph pattern using `projection()` before creating the 3d model. I think it would be useful to easily test out the spirograph pattern without generating the complex 3d geometry.
*   **Units:** The units should be in millimeters (mm), and the design should be suitable for 3D printing.

Essentially, I want to take the spirograph concept and make it very customizable, and not be limited to the example I have provided.

I anticipate that this will use OpenSCAD's built-in functions and maybe some simple math functions. I would also like to make use of the `BOSL2` library for vector and path handling as well as the smoother `linear_extrude`.

Okay, I'm looking to create a parametric picture frame design in OpenSCAD, and I'd like some help building it. I have a specific aesthetic in mind, and I'm hoping to make it very customizable for different print sizes and personalizations. I'm including a description of my current design and my goals.

Here’s what I’m aiming for:

**Core Design:**

*   The picture frame should have a classic, woodworking-inspired design, featuring a cove-shaped profile on the inner edge.
*   The frame needs a rabbet on the back to hold the picture, backing material, and possibly a piece of glass or clear plastic. This rabbet needs to be configurable for different material thicknesses.
*   I want the frame to have text engraved on the curved cove profile, so it follows the curve of the cove. This needs to be fully customizable, allowing different messages on the top, bottom, left, and right sides of the frame.
*   The backing plate should have a few small cylindrical tabs to hold it securely in the frame's rabbet.
*   The back plate should also have customizable text.

**Customization Goals:**

*   **Artwork Size:**  The core parameter is the size of the artwork to be framed (width and height, in mm).
*   **Frame Width:** The width of the frame border around the artwork (in mm).
*   **Frame Thickness:**  The overall thickness/depth of the frame (in mm).
*   **Cove Parameters:** I need to control the depth of the cove feature, the margin between the cove and the frame's edges, and therefore also the cove width.
*   **Rabbet Parameters:** I need to control both the width and depth of the rabbet on the back of the frame.
*   **Text Parameters:** I need to be able to input the text strings for the top, bottom, left, and right sides of the frame, as well as the text for the back plate. I also need to control:
    *   The font choice using a font file from the 'write' library.
    *   The font size (in mm).
    *   The space between characters.
    *   The thickness of the raised text.
*   **Back Plate Parameters:**  I need to control the thickness of the back plate, the clearance (offset) between the back plate and the frame opening, and the width of the retention tabs.

**Specific Functionality:**

*   The text on the cove should be engraved so that the text is raised, not cut into the frame. The text should follow the curve of the cove.
*   The text on the bottom of the frame needs to be inverted, so it's readable when the frame is viewed from the front. The code will have to invert the text.
*   The back plate should have an easy snap-in design using cylindrical tabs.

**Libraries:**

*   I’m already using a library called `write.scad` for the font rendering. I need to ensure this is included in the new design, and I need the `writecylinder` and `writecube` functions from that library.

**Output:**

*   I need a single .scad file that includes all of the parametric controls and produces the picture frame design.

Can you help me build this parametric picture frame design in OpenSCAD?

Okay, I'm looking for a way to create custom knobs for various projects and I want to use OpenSCAD to design them. I like the flexibility offered by the CustomizableKnob.scad file I've found. It has a lot of the features I'm looking for but it's not *quite* perfect for my needs.

I want a design that uses parameters to control all the major aspects, and I want it to be easily adjustable for a range of uses. I have some specific features that I care about, but I also want the generated OpenSCAD file to be well-commented and easy to use and modify further.

Here are the main features I need, and some notes about them:

*   **Hole Options**:
    *   The knob needs a central hole with a diameter and depth that I can set.
    *   I need an option for a D-shaped hole. I should be able to control the thickness of the flat part of the "D".
*   **Knob Body**:
    *   The overall height of the knob, without the dome or shaft, should be a parameter.
    *   The diameter of the main part of the knob needs to be adjustable.
    *   I need a "taper" option, where the knob can be a cylinder or taper from a larger diameter at the base to a smaller one at the top. I'd like to be able to specify the taper in terms of a percentage difference in diameter between the base and top.
*  **Top Shape**:
    *   I need a few options for the top shape: Flat, Recessed, and Domed. I'd like these as an enum type of sorts if that's easily doable. The recessed shape should be a cylindrical divot to allow for painting or labeling. The domed shape should be a dome on the top surface.
*   **Pointer/Direction**:
    *   I need options for visual indicators of direction: a timer-knob style pointer (a large conical or triangular pointer), a small divot on the top, and a line on the front. Each of these needs to be independently controlled by boolean parameters.
*   **Knurling**:
    *   I need the option to add knurled ridges around the knob, and that the knurling should be applied to the tapered surface when appropriate.
*   **Dial Ring**:
    *   I need an option for a dial ring around the base of the knob.
        *   I need to be able to control the width of this ring.
        *   I want the ability to add markings to the dial ring, controlled by the number of markings around it.
*   **Set Screw Hole**:
    *   I need an option for a set screw hole, and the diameter of this hole should be controlled by a parameter.
*   **Shaft Options**:
    *   I need an option for a shaft on the bottom of the knob.
        *   The length and diameter of the shaft should be controllable via parameters.
        *   I need an option for a notch on the shaft for press-on type attachment.
*   **Advanced Parameters**:
     *   The current code has some parameters like "RingThickness", "DivotDepth", etc. I would like to be able to change these if I need to, but they should be set to reasonable defaults.
*   **Code Quality**:
    *   I would like the code to be clean, well-formatted and easy to read.
    *   Use comments liberally to explain what parts of the design are doing and how the code is working.
    *   The code should not use any global variables outside of parameters (I see PI as a "global" in the current code, this should be avoided.) Use `PI = acos(-1);` when you need pi instead of hard-coding 3.1415.

I'm not looking to use any external libraries for this, I want it to be self-contained as a single .scad file.

Can you provide me with an OpenSCAD file based on these specifications?

[User]
Okay, I have this OpenSCAD design for a pond pump splitter, and I'd like to make it more flexible and easier to customize. It's currently set up to split the flow into a fixed number of tubes, but I want to be able to easily change that. Also, I think the base could be made a bit more robust with different mounting options.

Here’s what I have now. It uses a honeycomb structure to create laminar flow before splitting the water into smaller hoses, which I want to keep. The current code is attached (`PondPumpSplitterAdapter.scad`).

Here's what I'd like the new parametric design to be able to do:

1.  **Variable Output Count:**  Instead of being hardcoded to 3 output hoses, I want to be able to specify the number of output hoses/tubes through a variable (e.g., `output_count = 4;`). These should be evenly spaced around the circumference.

2.  **Hose/Tubing Parameters:** I need to be able to specify the inner and outer diameter of the tubing we are using (`tubing_outer_diameter = 6;` and `tubing_inner_diameter = 4;`).

3.  **Pump Outlet Diameter:** I need a parameter to define the diameter of the pump outlet/base input (`pump_housing_diameter = 19;`). I want this to be the diameter of the cylindrical portion, not the hole.

4.  **Base Height and Shape:** Instead of a simple cylinder, I'd like to have a parameter for the total base height (`base_height = 40;`) and another that controls the shape of the base from cylindrical to truncated cone.  I'd like to specify the diameter at the top of the base (`base_top_diameter`) to control the truncation.

5.  **Wall Thickness:** I need a parameter for the thickness of the walls throughout the model (`wall_thickness = 2;`). This includes the base, output ports, and the transitions.

6. **Laminar Flow Grid:** The current model uses a honeycomb structure for laminar flow using a radius parameter. I want to keep this feature, but I want to be able to set the radius and cell size independently and change the shape of the base grid. I want to add a type parameter to pick a grid type (e.g. `grid_type="hexagon"` or `"circle"`) and a radius parameter (`grid_radius = 2`).  The `grid_cell_size` would specify the size of individual cells.

7.  **Transition Smoothness:** I'd like to control the smoothness of the transition from the large input to the smaller output tubes with a `transition_smoothness` variable. This would control the number of facets of rounding cylinders (like the `smooth` variable in the original file).

8.  **Mounting Options:**  I want to be able to add optional mounting flanges or holes to the base. A `mounting_type` parameter could control this, with values like `"none"`, `"flange"`, or `"holes"`. If "flange", we'd add a circular flange around the base with `flange_thickness` and `flange_diameter` parameters. If "holes", we'd add a number of mounting holes evenly spaced on the flange.

9. **Support Beam:** I'd like to keep the supporting hexagon beam.  It should use the same grid cell size as the laminar flow generator. I should be able to adjust its height.

10.  **Unit Compatibility**: This design needs to work for metric units (mm). Please ensure all calculations are in metric and any units are declared within the comments.

Ideally, the design should be parametric, meaning all of these options are controlled by variables at the top of the file, which are commented appropriately.

For libraries, please use the `BOSL2` library, if it makes sense. I'm already familiar with its features.

Could you please generate the OpenSCAD file with these features? Thanks!
