Okay, I'd like to create a customizable garden sign, something similar to the "Vegetable garden signs" on Thingiverse, but more focused on being easy to customize with text. I'm not too worried about stylistic flourishes; I just need a functional sign that I can generate with different labels.

Here's what I'm envisioning:

*   **Text Customization:** The primary feature needs to be the ability to change the text on the sign.  I'll need a variable to specify the text string.
*   **Font Selection:** I'd like to be able to pick the font used for the text. The code I have uses a 'font' variable and references .dxf font files in a 'write' folder, which seems to work well, so that should be kept. So I'll need a way to chose between different font options.
*   **Sign Body:** The sign needs a simple rectangular body behind the text to make it look solid.  It should be long enough to contain the text plus a bit extra. The text should appear to sit just above a thin rectangle that represents the "body".
*   **Stakes:** The sign needs two stakes to stick into the ground. I like the basic stakes in the existing design, but maybe they can be a little more robust and not intersect with the main body?
*   **Customizable Size:** Ideally I would like to control the height of the text to make the signs of a bigger or smaller scale.

I am also including the current code. This includes the `write/Write.scad` and `utils/build_plate.scad` files; I understand I'm not going to get those files from you since they are not part of my main code.

Could you write a parametric OpenSCAD file that allows me to do this? I'd like to keep the usage of the `write()` module for rendering the text; it looks like it comes from the `write/Write.scad` file that I am already using.

Okay, I'm looking to create a customizable battery holder for coin cell batteries, similar to the one found on Thingiverse (http://www.thingiverse.com/thing:21041) but much more flexible.

I need a design that lets me specify:

*   **Number of slots:** The number of coin cell batteries the holder should hold, let's call this `nr`. I'd like to be able to specify a value between, say, 5 and 25.
*   **Battery type:** I need to be able to select a standard battery type from a dropdown list, specifically `CR2032` and `AG13`, or choose a custom size. Let's call this variable `battery`.
*   **Custom battery dimensions:** If `custom` is selected for the `battery` variable, I need two additional parameters: `custom_radius` and `custom_width`, which define the radius and width of the custom battery.
*   **Divider width:** The width of the dividers between each battery slot should also be adjustable, let's call this `sizedivider`. I'd suggest using this to be twice the nozzle diameter of the 3D printer.

The design should have these features:

*   A base with dividers to separate the batteries.
*   The dividers should be circular sections oriented such that the flat side makes contact with the base and provides a sort of shelf to support the batteries.
*   The design should have walls on the long sides of the divider to ensure the batteries don't escape.

Could you please write an OpenSCAD file that is parameterized like this?

I'm not specifying the MCAD, BOSL, BOSL2, dotSCAD, NopSCADlib, or BOLTS libraries. I would prefer to do it all with vanilla OpenSCAD if possible. I'm also not specifying any specific file names for the included libraries.

Okay, I'm looking to design a parametric button battery clip holder, and I've found a good starting point but need some changes and would like to have the whole thing be driven by parameters.

The current design, which I've included in `buttonbatterypack.scad`, is pretty close. It creates a holder for button batteries, specifically either CR2032 or AG13, or a custom size, with a way to connect leads to the battery. I like that it includes a small ring to attach it to things.

Here's what I need from you:

1.  **Make it fully parametric.** I want to be able to control the battery size (radius and width), the edge thickness of the plastic, and the size of the attachment ring, all with clearly defined variables. The current file uses `custom_radius`, `custom_width`, and `edge` but these aren't very descriptive and could be improved. It'd be nice if there were a consistent naming scheme for this too.

2.  **Clear Parameter Definitions**: When I specify the battery size, I want to specify the `battery_radius` and `battery_width`, and not have them hard coded. Right now, it uses some hard coded values for `radius` and `width` inside the holder module which is less than ideal. When using predefined battery types, those sizes should override the custom sizes. For example, if I choose a CR2032 it should automatically use those dimensions, even if I've set custom sizes.

3. **Modular Design:** The holder is composed of several different pieces: the base, the divider, the attachment ring, and the clips. I would like each of these to be in its own module so I can reuse these for future designs. I would like each of these modules to expose their own unique parameters that make them customizable and allow for easy modifications.

4. **Consistent variable names**: In the current file I have some inconsistencies in naming for the modules that could be improved. Specifically, `radius` and `width` are used in the `divider` module and the `holder` module. I would like the use of a more consistent naming scheme with descriptive variable names to avoid any ambiguity.

5. **Improved Clip Design:** The method for holding the battery is fairly basic, just a gap to wedge the battery in. I would like for this to be slightly more aggressive, maybe with angled clips that actively grip the battery. The current way has the clips as a rectangle, which does not promote gripping, and also has those extra cylinders within the clips, and that looks inefficient and not clean.

6.  **Attachment Ring Customization:** The current ring is pretty simple and doesn't have any customization. I want to specify not just the ring radius but also the ring thickness. And for modularity, I'd also like to have the ring be in it's own module as well.

7.  **Use BOSL2:** I would like for the new design to use the BOSL2 library for any helpful functions or module and provide the proper imports.

8.  **Provide comments.** Be sure to comment the code to make it easy to read and understand.

So, to summarize, I need a parametric OpenSCAD file for a button battery clip holder using BOSL2, with modules for each part, well-defined variables and clear definitions for them, improved clips for holding the battery, and a customizable attachment ring. Also, ensure that pre-defined battery options use the correct size.

Can you create that for me?

Okay, I'm looking to create a parametric design for a bearing holder, specifically for LM8UU linear bearings, that will allow them to be mounted on a y-carriage designed for SC10UU bearings. I have an existing design that I'd like to use as a starting point, but I need it to be much more adaptable to different bearing sizes and mounting hole configurations.

Here's what I'm looking for:

*   **Bearing Support:** The design should hold a cylindrical linear bearing, specifically an LM8UU for the base case, but it should be parametric so I can easily change that to other sizes. The bearing should be held securely from the sides, essentially 'clamped' in place. It needs to be as low profile as possible, essentially zero vertical height relative to a mounting plate.

*   **Mounting Holes:** The design should have mounting holes that match the common SC10UU hole pattern, which in my specific case are spaced 28mm apart in the x-direction and 21mm in the y-direction. I need these to be adjustable, as I might need to adapt it to different hole patterns in the future. The mounting holes should be designed for M5 bolts.

*   **Bolt and Nut Recesses:** The design needs to include recesses or pockets for the M5 bolt heads and nuts. Ideally, it should also include some space for washers. I am using 20mm bolts, 6mm alu plate, 4mm nuts, and 1mm washers, but these should be parameters.

*   **Cut-Out Angle:** I'd like to retain the angled cut-offs in the original design to allow more access. The angle of the holder and bearing cutoffs should be parametric.

*   **Parametric Design:** Most importantly, I need this entire design to be parametric, so I can easily adjust the following:
    *   Bearing diameter
    *   Bearing length
    *   X distance between mounting holes
    *   Y distance between mounting holes
    *   Bolt diameter
    *   Nut diameter
    *   Washer size
    *   Bolt length
    *   Thickness of the mounting plate
    *   Cutoff angle
    *   Bearing cutoff angle
    *   A vertical offset parameter
    *   Size of the center rod cutout

*   **OpenSCAD:** The design should be created in OpenSCAD. Please use good code practices, and comment as needed to help make it readable. I prefer using only the core OpenSCAD libraries, as this will help me avoid dependencies. I need two main modules, one for the single bracket and one for the two side-by-side ones.

The original design that I've been using can be seen here:

Okay, I'm looking to create a customizable OpenSCAD design for Yale-style keys. I've been using the code I found [attached: yale_v5.scad], and it works pretty well, but I'd like to make it more robust and easier to adjust. I'd also like to make sure it's easily printed in different orientations.

Here's what I need the design to do, and the parameters I'd like to be able to control:

**Core Functionality:**

*   **Yale Key Profile:** The design should generate a key blank that matches the Yale key profile, including the main shaft with its characteristic grooves.
*   **Pin Notches:** It should generate the correct pin cutouts on the blade of the key (the notches)
*   **Grip/Handle:** It should have a grip section that is customizable, and a stopper/spacer between the grip and shaft.
*   **Text & Marking:** I'd like the option to add text on the grip and numbers (representing the notch cuts) on the blade.
*   **Print Ready Option:** I need an option to rotate the model for easy printing, with the key laying flat.

**Key Parameters (User Customizable):**

*   **`grip_text`:**  Text to be embossed on the grip (string).
*   **`notch1` - `notch5`:** Integer values [0-9] representing the depth of each of the five pin notches, closest to the tip (notch1) to the handle (notch5).
*   **`pattern_offset`:**  Offset of the key pattern/notches from the tip (in millimeters, [3-10]).
*   **`cutter_style`:** Option to choose between a simple cutter shape or a more advanced profile for cutting the notches (0 = Normal, 1 = Enhanced).
*   **`print_ready`:** Controls if the model is rotated for printing or not (0 = No, 1 = Yes, 2 = inverted).
*   **`shaft_length`:**  Length of the key shaft in millimeters ([20-35]).
*   **`shaft_height`:**  Height (thickness) of the key shaft in millimeters ([5-10]).
*   **`key_width`:** Width of the key in millimeters ([1.8, 1.9, 2.0, 2.1, 2.2]).
*   **`grip_radius`:** Radius of the grip in millimeters ([10-17]).
*   **`stop_width`:** Width of the stopper between the grip and the shaft in millimeters ([2-5]).

**Detailed Design Requests:**

*   **Grooves:** The key grooves need to be accurately reproduced. The attached file contains a `poly_groove` module that might be useful.
*   **Notch Cutting:** Make sure there are two cutting styles available; simple flat cuts, and a more advanced profile, as found in the provided file in the comments where `cutter_style==1`.
*   **Shaft:** The shaft should be a basic rectangular shape with rounded edges where appropriate.
*   **Grip:** The grip should be a cylinder with a circular cross section.
*   **Text:**  The grip text should be embossed/debossed on the grip in a way that is easy to print. The cut numbers must also be readable and clear on the blade of the key.
*   **Printing:** The `print_ready` parameter should rotate the model by 90 degrees so the key can print flat on the bed. Print_ready = 2 should output an inverted design.
*   **Libraries:** I'm using `Write.scad` from the `write` library. Please ensure you don't include other libraries unless necessary.

**Overall Goal:**

I want an easily customizable OpenSCAD module that generates Yale-compatible keys, that has clearly marked cut settings to make it printable. The attached file demonstrates the desired functionality, but it needs to be more robust, more modular, and use good OpenSCAD coding practices.

Please generate the OpenSCAD code based on these requirements.

Okay, I need help designing a customizable portion control container using OpenSCAD. I'm looking for something where I can easily adjust the size of the box and also how tall it is. I'd also like two handles on the sides, which should be a little shorter than the box and relatively thin.

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

*   **`container_size_dimension`**: This will control the width and depth of the container (it'll be a cube in those dimensions). I want to be able to set this value, and I want the container to be centered.
*   **`container_size_z`**: This will control the height of the container. This should also be adjustable and the container should be centered in the Z direction.
*   **`handle_x`**: This should be dependent on the `container_size_dimension` I set. It should be 2/3 the length of the `container_size_dimension`.
*   **`handle_y`**: This should be a constant dimension for the width of the handle. Perhaps 15 units as a good default.
*   **`handle_z`**: This will control the height of the handle. Perhaps 2 units for a good default.

The basic design should be a cube with a slightly smaller cube subtracted to create an interior cavity. Then the two handles are placed on the sides.

So, to summarize, I need an OpenSCAD file that defines a parametric portion control box with adjustable dimensions and handles. The container should have a hollowed-out interior. The handles should be on opposite sides of the box and their dimensions should be dependent on the container dimensions. Please also use comments in the code to explain how all of the code works.

Can you help me with this? I'd prefer it if we didn't use any external libraries.

Okay, I need a customizable button battery holder for my electronics projects, and I'd like it to be parametric so I can easily adjust it for different battery sizes and mounting configurations.

Here's what I'm looking for:

**Core Functionality:**

*   **Battery Compatibility:** I need to support multiple button battery sizes. Specifically, I'd like to predefine it for common sizes like CR2032 and AG13, but I also need a way to specify *custom* battery sizes. When a custom size is selected, I'd like to specify the radius and width of the battery.
*   **Wire Connections:** The design should have integrated holes for wires, allowing them to make contact with the battery without soldering. I envision a design where a wire can be looped through a set of back holes and a second wire is then threaded through a set of front holes, pressing against the battery faces.
*   **Parametric Design:** Everything should be adjustable via parameters. This includes:
    *   The battery type (CR2032, AG13, custom).
    *   If custom, the battery radius and width.
    *   The width of the edges/walls of the holder.
    *   The radius of the wire holes.
    *   The number of holders in the x and y directions (for creating arrays/racks of holders).
    *   The distance between holders in the x and y directions.

**Detailed Design Considerations:**

*   **Wire Holes:** It looks like there should be two wire holes in the back, and two on the face for the second wire (per the description). The holes should be large enough to pass wire through, but not so large as to interfere with the battery's electrical contact points.
*   **Battery Retention:** The design needs to hold the battery securely while allowing it to be inserted and removed with relative ease.
*   **"Ring to hang":** There is a "ring to hang it to something" near the wire hole. Please include this feature.
*   **Build Plate Display:** This is optional, but it would be nice if the design also included a way to display the build plate for reference. This is mostly for design purposes, and does not contribute to the final object. I would need options for Replicator 2, Replicator, Thingomatic, and manual. For manual, I will need to be able to specify the x and y dimensions.
*   **Units:** I'm working with millimeters (mm).
*   **Libraries**: I would like to use the MCAD library for font support, and I am also using utils/build_plate.scad, though I don't think that's a part of any standard library.

**Output**

I am looking for a single OpenSCAD file that encapsulates the entire design and utilizes the libraries specified.

Could you generate the OpenSCAD code for this?

Okay, I'm looking to create a library of PCB standoffs in OpenSCAD, and I'd like it to be flexible enough to handle different needs. I've been looking at existing libraries and like the functionality of `pcb_stand_off_v1.3.scad`, but I need something more robust and maintainable. It needs to function both as a standalone customizable object *and* as a library to be included in other designs.

Here's what I need:

**Core Functionality:**

1.  **Multiple Standoff Types:**  I need to be able to generate three main types of standoffs:
    *   **Plain:** A simple cylindrical standoff with a through-hole.
    *   **End Nut:** A standoff with a captive nut feature at both ends, probably using the `flat_nut` module from the `MCAD` library.
    *   **Split Base:** A screwless standoff with a base, a support pillar, and a "snap-in" feature that grips the PCB.

2.  **Shape Options:**
    *   The "plain" and "end nut" types should allow for either a circular or hexagonal outer shape. The "split base" type only needs a circular shape.

3.  **Parametric Design:** Everything should be fully parametric, meaning I need to control the following parameters:
    *   `od` (Outside Diameter): The diameter of the main body of the standoff.
    *   `id` (Inside Diameter): The size of the through-hole for a screw, and the internal diameter for the captive nuts or split base pillar.
    *   `len` (Length): The overall length of the standoff or support height for split type.
    *  `cl` (Clearance): A clearance value to be applied to the through-hole or internal diameters
    *   `thk_base` (Base Thickness): The thickness of the base for the `split_base` standoff.
    *   `thk_pcb` (PCB Thickness): Used for the snap fit calculation in the `split_base` standoff.

4.  **Library and Customizer:**
    *   The scad file should work as a library, where I can include it and call `pcb_stand_off()` with all the mentioned parameters.
    *   I also want it to work as a standalone file, where I can use a customizer with the parameters to quickly generate a single standoff of my choosing.

5.  **Dependencies:**
    *   I would expect the design to use the `metric_fastners.scad` module from the `MCAD` library for the nut feature in "end nut" standoff. I don't need to include a copy of that module in the new file.

**Specific requests for the split base standoff:**

*   Please include named parameters for the support pillar diameter and support angle, as well as a parameter to control the top section length (the section above the pcb with a reduced diameter). It should also still take the `id` parameter and apply the clearance to that as an internal diameter of the pillar.
*    The "snap-in" feature should have the correct clearance and length to securely hold the PCB, based on the `thk_pcb` parameter.

**Output Expectations:**

*   I need a single OpenSCAD (.scad) file that contains all the necessary modules and logic.
*   I'd like a set of commented-out test cases showing various instantiations of all the stand-off types to make sure it's working correctly.
*   It would be great if all the modules and parameters were appropriately commented for clarity.

Essentially, I'm looking for a cleaner, more robust version of the provided `pcb_stand_off_v1.3.scad` that I can rely on. Can you generate that for me?

Okay, I'd like to design a customizable shelf talker, similar to the one I found online, but with some added flexibility. I've seen some designs that are okay, but I want something that lets me really tweak the look and feel.

Here’s what I’m looking for:

**Core Functionality:**

*   **Text Label:** The shelf talker should prominently display a text label. This text should be customizable.
*   **Font Control:** I need to be able to change the font style, font size, and letter spacing. The design I saw online used DXF fonts (which is fine), but I should also be able to use built-in fonts if I want.
*   **Shelf Thickness:** The design should accommodate different shelf thicknesses. I need a parameter to control the thickness of the shelf the talker is designed to grip.
*   **Attachment:** It should securely attach to the shelf edge, probably with a hook or lip at the back.

**Additional Customization Features:**

*   **Text Alignment:** I'd like to be able to control the text alignment – left, center, or right justified, within the available space.
*   **Text Rotation:** Ability to rotate the text, for example, to make the label vertical instead of horizontal.
*   **Overall Width:** I’d like to have a parameter for the total length/width of the talker, not just based on the length of the text. I might want a specific length, and want the text to fit within it. The width could be auto-calculated too if the width parameter is not explicitly defined.
*   **Text Placement:** Option to adjust the placement of the text block within the overall talker width.

**General Design Considerations:**

*   **Parametric Design:** It should be entirely parametric using OpenSCAD so I can easily change all of these parameters.
*   **Robustness:** I'd like the design to be reasonably sturdy, so some thought about support and thickness of the plastic elements should be taken into account.
*   **Ease of Use:** The parameters should be relatively intuitive to use.
*   **Use Libraries:** Please use the write library that the original example used so that I have the DXF font support. I am happy to use any other library that makes the code cleaner or more functional.

**Here's some inspiration from the design I found:**

The design I'm basing this on uses these libraries:

*   `write/Write.scad` (for DXF font support)
*   `utils/build_plate.scad` (though I don't need the build plate preview itself - it is just a convenience feature to define the size of the bed)

I’d like to get something with similar functionality, but with the added flexibility I mentioned above. Can you please help me create an OpenSCAD file for this?

Okay, I need a parametric OpenSCAD design for mounting hobby servos to an optics breadboard, but I'd like a few specific changes and to make it more flexible.

Here's what I'm looking for:

**Core Functionality:**

*   The design should mount a standard hobby servo to an optics breadboard.
*   The base will attach to the breadboard via slots that are a multiple of the breadboard grid spacing. The slots should be long enough to allow for some adjustment.
*   The servo is mounted on posts connected to the base.
*   The servo mounting holes should be parametric and allow for both hole and slot shapes.

**Specific Requirements based on the example I have:**

*   **Breadboard Compatibility:**
    *   The breadboard grid spacing should be parametric.
    *   The clearance hole diameter for the breadboard mounting screws should be parametric.
    *   The number of mounting holes to be covered in both X and Y directions should be parametric.
    *   The clearance around the mounting slots should be parametric.
*   **Servo Mounting:**
    *   The distance between the servo mounting holes should be parametric.
    *   The mounting screw diameter should be parametric.
    *   The offset of the servo spline from the center of the mounting screws should be parametric.
    *   The desired height of the servo spline should be parametric (assuming the mounting screws are at a reference height)
    *   The thickness around mounting holes on posts should be parametric.
    *   The post width should be parametric.
*   **Base:**
    *   The base thickness should be parametric.
*   **General:**
    *   The design should use reasonable OpenSCAD best practices for maintainability and customizability.
    *   I'd like to be able to change the render resolution through `$fa` and `$fs`.

**Desired Changes/Additions:**

*   **Servo Orientation:** I'd like to be able to specify an additional parameter for the servo orientation, so the whole mounting assembly can be rotated in the XY plane. This should allow us to mount servos on all four sides of a breadboard.
*   **Base Shape:** Instead of a simple rectangle, I'd like the base shape to be more customizable, possibly having a set of predefined shapes (rectangle, circle, rounded rectangle). If possible, allow a custom shape to be imported as a DXF.
*   **Multiple Servos:**  It would be great if the design could be easily modified to mount multiple servos on a single base.  Maybe this could be an additional parameter or function, letting me place multiple servo mounts on the base and adjust their positions relative to each other.
*   **Library Usage:** I'm open to using standard OpenSCAD libraries if that would improve the design, such as the BOSL libraries, or others you may recommend.

**Summary:**

I need a highly parametric OpenSCAD module for mounting hobby servos to optics breadboards, with the flexibility to handle different servos, breadboards, mounting positions, base shapes, and the ability to mount multiple servos. I'd also like to add the capability for servo mount rotation in the XY plane, a customizable base shape (or a set of base shapes) and to be able to import a custom base shape using DXF. I'd also like to be able to place multiple mounts on the base. Please use any useful libraries you deem appropriate.

Okay, I'm looking to create a 3D printable coin game, kind of like a simple pegboard but with sliding steps. I've got a basic idea in my head, and I'd like to have it designed in OpenSCAD so I can customize it.

Here's the basic layout I'm thinking of:

*   **The Game Board:** It consists of a bottom plate, a top plate, and the game mechanics which are sandwiched in between.
*   **The Coins:** The game has a set of coins that sit on top of a step-like mechanism. I'd like these to be circular. The coins should have a small margin so they don't bind.
*   **The Steps:** The coins rest on steps that are arranged in a grid. Each column of steps is slightly lower than the one beside it. These steps need to allow the coins to slide down into the bottom of the board.
*   **The Grid:** The steps are arranged in a grid pattern, forming columns and rows. The lines forming the grid should also be part of the model.
*   **Coin Catcher/Exit:** At the end of the steps I would like an angled section to catch the coin and also allow to take the coin out from the game board, this section need a way to constraint the coin when the user rotate the game board.
*   **Text:** I would like to have customizable text printed on the top plate of the game using a decorative font.
*   **Parametric Design:** I want the whole thing to be parametric so I can easily adjust things like the coin diameter, the number of coins, the number of lines of the grid, margins, text height, and so on.

Here are the specific parameters I envision:

**Global:**
* `part`: A string parameter that allows to show the "Preview", the "Top" part, the "Coins" or the "Bottom" part for easy debug.

**Sizes:**
*   `coin_diameter`: The diameter of the coins.
*   `coin_height`: The thickness of the coins.
*   `coin_number`: The number of coins in a column.
*   `line_number`: The number of lines (or columns) in the grid.
*   `line_margin`: The spacing between lines/columns.
*   `layer_height`: The layer height for 3D printing.
*   `extrusion_width`: The extrusion width for 3D printing.
*   `xy_margin`: An xy margin to allow for moving parts.
*   `z_margin`: A z margin to allow for moving parts.
*   `top_plate_height`: The height of the top plate.
*  `plate_min_height`: The minimum height of the bottom plate.
*  `slider_min_radius`: The minimum radius for the coin guide.
*  `slider_increment`: The radius increment for the coin guide.
*  `coin_catcher_hardness`: The thickness of the coin catcher's angled face.
*  `coin_catcher_height`: The height of the coin catcher section.
*  `coin_catcher_margin`: The margin for the coin catcher sides.

**Text:**
*   `text`: The text to be displayed on the top plate.
*   `text_font`: The font to use for the text (using fonts from the `write/` folder from the `Write.scad` library)
*  `text_space`: The spacing for the text letters
*   `text_height`: The height of the text. (Set to 0 to hide)
*   `font_thickness`: The thickness of the font.

**Functionality/Layout:**

*   **Plate:** Need a module to create plates with rounded corners.
*   **Coins:** Need a module to create the coins, with circular base, sitting on a circle guide.
*   **Steps:** A module that creates stepped cylinders that the coins rest on.
*   **Lines:** Module to create the grid lines/columns.
*   **Coin Catcher/Exit:** A module that creates the slanted piece to catch and exit coins.

**Libraries:**

*   I'm using the `Write.scad` library from the `write/` folder for the text functionality.

I would like the output as a single OpenSCAD `.scad` file. Please use comments to indicate where you implement the different modules.

Can you help me generate the OpenSCAD code for this?

Okay, I'm looking to make a customizable die with text on each face, and I'd like to use a low-poly font. I found this existing OpenSCAD file that does most of what I want, but it's a bit clunky and I'd like to make it more parametric and easier to use.

Here's what I'm aiming for:

**Core Functionality:**

*   **Dice Shape:** The base of the design should be a cube with rounded edges (like the `fcube` module in the provided file).
*   **Text on Faces:** I want to be able to put different text on each of the six faces of the cube. I'd like to use the low-poly font provided in the linked file.
*   **Customizable Text:** I need to easily change the text for each face.
*   **Text Depth:** I need to control how deep the text is recessed into the die face.
*   **Text Scale:** I need to be able to adjust the overall size of the text. I’d also like control over the size of each text individually.
*  **Die Size:** I need to be able to change the overall size of the die itself (the length of each side).
*  **Edge Width:** I need to control the width of the rounded edges.

**Desired Parameters:**

*   `die_size` (the length of each side of the die cube)
*   `edge_width` (the width of the rounded edge)
*   `text_depth` (how deep the text is recessed)
*   `overall_text_scale` (a global scale factor for all text)
*   `text1`, `text2`, `text3`, `text4`, `text5`, `text6` (the text strings for each of the six faces)
*   `text1_scale`, `text2_scale`, `text3_scale`, `text4_scale`, `text5_scale`, `text6_scale` (individual scale factors for each text)

**Additional Requirements:**

*   The text should be centered on each face.
*  The low-poly font from the `lowpolyfont v1_0.scad` file (included at the end of the provided file) should be directly included in the final `.scad` file; I don't want to rely on an external file reference. The font itself only needs to support the characters available in this string: `" ABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890.:!?"`.
* I want to keep the `$fn=32` for the rounded edge.

I’m not looking to include any other features from the included file like the sign. Also the color definitions and other parameters can be removed, as well as the functions for calculating the length of a text string.

Could you generate an OpenSCAD file that implements these requirements? I'm basically trying to make a parametric version of the attached design, with the modifications specified.

Okay, I need a customizable phone stand designed in OpenSCAD. I want to be able to print it on its side without needing supports.

Here are the key features I'd like:

*   **Base:** The base should be a rectangular flat surface. I need to be able to control the width and length of this base. I also need to set the thickness of the material (wall thickness).
*   **Back Support:** I want a sloped back support that extends upwards from the back edge of the base. I should be able to control the height of this support and the angle of its slope.
*   **Front Support:** Similar to the back, I need a sloped front support extending from where the back support ends. I should be able to control the height and angle of this front support. It should come down to approximately the same y-level as the base.
*   **Tray:**  There should be a tray to hold the phone. This tray will be formed by a flat, angled section extending from the bottom of the front support. I should be able to control the length of this flat tray portion and the angle it makes with the vertical (the angle should be settable beyond the normal 90 degrees so you have a way to invert it to hold a phone, so 340 degrees instead of -20, for example). Then, there needs to be a small lip at the end of the tray, which acts as a stop. I need to control the length of the tray lip.

Also, it’s really important that I can export this to an STL that prints *on its side*. To achieve this, I’d like a parameter that switches between “preview” mode and “print” mode. When I select "print" mode, the whole model should be rotated 90 degrees around the y-axis before rendering. That way, I can print it without supports, with all the flat surfaces touching the build plate.

Finally, I need a small "fuzz" parameter to prevent rendering glitches.

I've included my existing .scad file for reference. Please create an improved version.

Okay, I'm looking to design some small clips for holding a glass plate onto a bed, like on a 3D printer. I've got a basic design in mind, and I'd like to make it fully parametric in OpenSCAD so I can easily adjust it for different thicknesses.

Here's what I'm trying to achieve:

*   **The basic shape:** The clip should be a sort of "U" shape. One side of the "U" will clamp down on the bed, and the other side will clamp down on the glass.
*   **Parametric variables:** I need to be able to adjust these values:
    *   `bed_thick`: The thickness of the bed.
    *   `glass_thick`: The thickness of the glass.
    *   `width`: The width of the clip.
    *   `clip_thick`: The thickness of the clip's bars.
    *   `depth`: How far the clip extends onto the glass and bed.
    *   `nub`: The "tightness" factor. This will control how much smaller the clamping nubs are compared to the combined thickness of the bed and glass. This should be a small value (e.g., 0.25).
*   **Construction details:**
    * The main body should have the "U" shape described above, creating a channel for the bed and glass.
    * There should be small circular nubs that extend from the inside edges of the U-shape. These nubs will actually grab and hold the glass and bed. These need to be smaller than the combined thickness by the 'nub' variable.
    * I want to ensure that the overall clip extends beyond the bed and glass to allow for full clamping.
*   **Final design:**
    * I'd like the clip to be fairly simple in design and should be fully 3D printable.

Could you generate an OpenSCAD file that takes these parameters and constructs this clip design?  I'd like to avoid using any external libraries if possible to keep it simple. Thanks!
