Okay, I'm looking to design a customizable license plate frame that I can 3D print. I've seen some cool ones online, and I'd like to have the ability to add text, symbols, and even choose between a full-size or split-size frame for smaller printers. The design should have mounting holes for the license plate and, if possible, interlocking tenons/mortises if I choose the split design. I want to use OpenSCAD for this.

Specifically, here's what I'm hoping for in the design:

**Frame Size:**

*   I need a parameter to choose between a **FULL** size (311.8mm wide) or a **SPLIT** size (155.9mm wide) version. This is mainly for people with smaller build plates who need to print the frame in two pieces. If `plate` is set to `155.9`, then the model should be split along the horizontal center and have a tenon/mortise join. If it is `311.8`, the model should be a single plate frame.

**Text:**

*   I need to be able to add text along the top and bottom edges of the frame. Let's call these `top_text` and `bottom_text`.
*   I'd like to choose the font for the text, such as "Helvetica:style=Bold", which can be stored as a `text_font` string parameter.
*   There needs to be a way to change the size of the text using a `text_size` parameter.
*   I want to control the depth of the text, whether it's recessed into the frame or raised above it. I need both a `text_height` and a `text_depth` parameter. `text_depth` should determine the recess amount, and `text_height` should represent either the total thickness of the text when raised or the depth the text is cut out from the frame when recessed. A third `is_raised` parameter would decide this. If it is set to 0 the text will be recessed. If it is 1, the text will be raised, and if 2, then text will be raised but not include the frame.
*   I need offset parameters (`top_shift` and `bottom_shift`, each a 3D vector) to adjust the horizontal and vertical positioning of the text. This is mainly to center the text properly since not all fonts are monospace.
* I also need to put vertical text along the left and right side of the frame, each having a string variable (`left_text`, `right_text`) and a corresponding font size parameter (`vtext_size`). I'd like the text to be aligned top-to-bottom, and centered. It should be placed on the outer edge of the plate.

**Symbols:**

*   I'd like to include symbols near the mounting holes. There should be a `sym_text` parameter to set what character to use for the symbol and `sym_size` to set the font size of the symbol. I'm thinking maybe emojis or basic shapes. There will be `top_sym_shift` and `bot_sym_shift`, 3D vectors, to adjust the placement of the symbol on the top and bottom, respectively.

**Preview/Display:**

*   I would like to set colors for previewing the frame and text. The text color should be `text_color`, the frame should be `framecolor`, and the text box (the base frame upon which all the other objects are built) should be `textboxcolor`.

**Frame Details:**

* The frame thickness should be around 6.35mm or about 1/4".
*   I need standard mounting holes for a license plate.

**Libraries:**

*   I know I'll need the `MCAD` library, specifically `shapes.scad` and `fonts.scad`.
*   I'll also need the `text_on` library, which I believe is in `text_on/text_on.scad`. It needs to be parametric. I want to make use of text\_extrude().
*   I should be able to set `font_scale`, `x_shift`, and `y_shift` (which comes from the 8bit font call).

**Other:**
*   I would like the text and symbols to be placed such that I can adjust their shifts independently of one another. I don't want to have to recalculate everything every time I want to adjust a font or a symbol's position.
*  I would like the design to be parametric, so I can change the dimensions easily in the code.

I think that covers everything. Could you generate the OpenSCAD files for me?

Okay, I'm looking for an OpenSCAD tool to help me modify STL files for 3D printing, specifically for model train stuff. I've seen a couple of versions floating around, but I'd really like something parametric and more flexible.

Here's what I need it to do:

**Core Functionality:**

*   **Import STL:** I need to be able to import an STL file as the base object that I'll be modifying.
*   **Resizing:**
    *   **Manual Scaling:** I need to be able to scale the object by a percentage using a single input - like a global scale factor. I can use a customizer slider to set the scale as a percent (e.g. 100%, 50%, 200%).
    *   **Model Train Scale Presets:** It needs to include a dropdown list for common model train scales. This should include: II, I, O-48, O-45, O-43.5, S, OO, HO, TT, N, Z, ZZ-285, ZZ-300, T-450, and T-480. When I select a source and destination scale, the object should automatically rescale based on the ratio of those scales. The value list for the scales are: 22.5, 32, 48, 45, 43.5, 64, 76.2, 87, 120, 160, 220, 285, 300, 450, and 480, respectively.
*   **Positioning:**
    *   **Linear Translation:** I need to be able to move the base object along the X, Y, and Z axes. I'd like both coarse positioning (integer values) AND fine positioning (fractional values), and also a way to move it globally with integer values.  So three controls for each axis.
    *   **Angular Rotation:** I need to be able to rotate the base object around the X, Y, and Z axes using degrees.
*   **Add/Subtract Operations:**
    *   **Import STL:** Allow me to import a second STL object that I can either add or subtract (cut) from the base object.
    *   **Primitives:** Allow me to add or subtract (drill) basic shapes, specifically:
        *   **Cylinders:** I need to be able to control the diameter and the height (depth) of the cylinder, with an option to use a cone instead of a cylinder. The cone will require 2 diameters and a height. I would also like to be able to deform the cylinder to an ellipse along one axis.
        *   **Cubes/Rectangular Prisms (Parallelipipeds):** I need to be able to control the X, Y, and Z dimensions of the cube.

* **Text Extrusion:**
   * I want to be able to add extruded text, or use extruded text to cut into the base object.  I need to be able to specify the text, font, size and extrusion depth. The position/rotation of the text needs to be controllable.
   *   The text object can be treated either as a "flat" 2d extrusion or as an extrusion on a cylinder or rectangular prism.  If the second case is used, the cylinder and rectangular prism options must include position and rotation control, like the regular primitives.  This might need a separate section for the text position vs. the cylinder/prism position, I'm not sure, it depends on how easy it is to handle.
*   **Visual Helpers:**
    *   **Ruler:** (Optional)  It would be awesome to have a visual 100mm ruler that I can enable/disable.  I should be able to control its position and rotation.  It should have a customizable color.
    *  **Coordinates:** I would like to have the coordinates, rotation values, and scale displayed somewhere in the visual output.

**Customizer UI:**

I'd expect to see these controls in the OpenSCAD customizer:

*   **File Inputs:**
    *   Base STL file name
    *   Optional STL file name (for add/subtract)
*   **General Options:**
    *   Checkbox to show or hide the ruler
    *   Dropdown for ruler color
    *   Checkbox to show or hide coordinates/scale
*   **Ruler Position/Rotation:**
    *   X, Y, and Z translation for the ruler.
    *  X, Y, and Z rotation for the ruler.
*   **Base Object Scaling:**
    *   Dropdown to choose "manual" or "scales" mode
    *   Scale percentage input (slider)
    *   Dropdowns for source and destination model train scale
*   **Base Object Positioning:**
    *   X, Y, and Z global translation (integers)
    *   X, Y, and Z  translation (integers)
   *    X, Y, and Z fine translation (fractional/decimal)
    *   X, Y, and Z axis rotation (degrees)
*   **Add/Subtract Options:**
    *   Dropdown to select "non", "add", or "subtract" for the operation.
    *   Dropdown to select the type: "STL Object", "Text", "Cylinder", "Prism" (parallelipiped), "Text on cylinder", "Text on cube/prism".
    *   For STL Object:
        *   STL filename
        *  X, Y, and Z translation for added/subtracted object.
         *  X, Y, and Z rotation for added/subtracted object.
    *   For Cylinder:
        *  X, Y, and Z translation
         *  X, Y, and Z rotation
       *   Dropdown to choose "cylinder" or "cone"
        *   Cylinder/cone diameter 1
        *  Cylinder/cone diameter 2
        *   Cylinder/cone height (depth)
      *   Cylinder/cone X-axis deformation for creating an ellipse.
    *   For Prism:
        *  X, Y, and Z translation for added/subtracted object.
         *  X, Y, and Z rotation for added/subtracted object.
        *   X, Y, and Z dimensions of the cube.
    *  For Text
        *   Text String
        *   Font Selection
        *   Text size
        *   Text extrusion depth
        *  X, Y, and Z translation for text object.
         *  X, Y, and Z rotation for text object.
    *  For "Text on Cylinder" or "Text on Prism":
        *  Text properties as above
        *   Primitive properties as above.

**Output:**

*   The tool should output a single STL file after rendering with all modifications applied.

I think that's everything! I'd like this to be really robust and user-friendly. Let me know if you have any questions.

[User]
Hey! I'm working on a small box project and I need a jig to help me drill consistent holes for barrel hinges. I've seen a design for a drill guide, but I'd like to have it made custom for my specific dimensions and allow for a few more features.

Here's what I'm thinking:

**Basic Shape:**
The guide should essentially be an L-shaped block that fits into the corner of my workpiece. One face of the L will butt against the side of the workpiece, and the other against the back.

**Hole Positioning:**
*   I need to be able to control the distance of the hole from the side and back edges of the workpiece. Let's call these `side_to_hole` and `back_to_hole` respectively.
*   The hole itself should be cylindrical, and its diameter needs to be customizable, `hole_diameter`, to accommodate different hinge sizes or drill bits.
*   I also need to set how deep the hole in the guide is, `hole_depth`, so that I can use it to guide my drill bit at the right depth.
*   I would like the hole to have a smooth shape, so lets set `hole_facets` which controls the number of polygons used to generate the cylinder

**Guide Structure:**
*   The L-shape needs to have "lips" or edges that contact the workpiece. I want to be able to set the size of those with a parameter, `lip_size`.
*   Also the thickness of the guide's edges needs to be adjustable, `edge_thickness`, although I probably won't need to adjust it much.
*   I would like to add extra distance beyond the hole location for extra support in the length and width of the jig, `guide_distance_past_hole`.

**Additional Features:**

*   **Parameter for Total Guide Thickness:** I'd like a parameter `total_guide_thickness` that automatically calculates the total thickness of the guide including the lips and the hole depth.
*   **Support for Multiple Holes:** It would be really helpful if I could specify a number of holes and their spacing along both the side and back. That is, I'd like to specify a `hole_count_side` for how many holes along the guide that will be aligned with the side, and `hole_count_back` to set how many will be aligned with the back edge. I need to set `hole_spacing_side` and `hole_spacing_back` respectively for the spacing between those holes. The guide length and width will need to grow to accommodate the number of holes.
*   **Optional Mounting Holes:** It would be great to have an option to add mounting holes on the guide for screwing it down, maybe using a boolean parameter called `add_mounting_holes`. We should set `mounting_hole_diameter`, and have them placed such that there are holes on each side of the cylinder and extend out from the guide body.

**Libraries:**

I'm not using any custom libraries, just the standard OpenSCAD functions.

Can you generate the OpenSCAD code for this? I think this will be super useful for my project!

Hey, I'm looking to create a parametric fan duct or adapter using OpenSCAD. I've seen some designs that use two fan plates connected by a tube, and I'd like to create something similar but with a lot of flexibility in terms of sizing and positioning.

Specifically, I need to define:

*   **Fan Plate Sizes and Shapes:** Both the inner and outer diameters of both fan plates need to be customizable. The plates will be square with rounded corners. I'll also need to be able to adjust the corner radius for each plate independently. I want to specify the thickness of each fan plate too.
*   **Screw Hole Placement:** The design should include screw holes for mounting the fans. I need to be able to set the offset of these holes from the edge of the fan plate and also the radius of the screw holes themselves, for both fan plates independently.
*   **Tube Connection:** The tube connecting the fan plates should have a defined thickness. I also need to adjust the z-distance between the two fan plates.
*   **Plate Positioning:** I need to be able to shift the smaller fan plate in the x and y directions relative to the larger plate, as well as rotate the smaller fan plate on the x and y axes.
*   **Corner Removal:** I need the ability to remove one or more of the quadrants from the larger fan plate. This is useful when space is limited in one direction.

I'd like to be able to configure all these parameters via variables at the top of the file, making it easy to customize the adapter for different fan sizes and mounting configurations. I don't think I need to specify units for any measurements.

I also would prefer to not be given any existing code to work off.

I think the basic idea can be achieved with core OpenSCAD modules. I'm not sure if this would be better as one large .scad file or multiple; if the design becomes complex, perhaps a small library would be useful, but if you think one .scad file is enough I'm open to that too.

Hey, I need help designing a replacement duct for my iFlight Green Hornet quadcopter. I've got some measurements and want a parametric OpenSCAD design so I can tweak things if needed.

Basically, it's a cylindrical duct with a few cutouts and a brim on both ends. Here are the key dimensions I'm working with:

*   **Overall Height:** 28.75 mm
*   **Inner Diameter:** 78.4 mm
*   **Wall Thickness:** 1.3 mm
*   **Slit Width:** 7 mm
*   **Standard Slit Height:** 2 mm
*   **Cable Slit Height:** 4mm
*   **Standoff Diameter:** 4 mm

There will be three slits equally spaced around the circumference of the cylinder. One slit (for the motor wires) should have a height of 4mm, and the other two should have a height of 2mm. Each slit extends all the way to the outer radius of the cylinder. There also needs to be a cylindrical standoff at each of the locations of the three slits, centered at the outer radius.

I also want to add a "brim" on both ends, like a little flange for better adhesion during printing. I'd like the brim to be made up of cylinders that are 2mm tall with a 2mm radius. The brim needs to have a few additional features to make it a single continuous extrusion around the cylinder:
   *   A circular 'loop' of these 2mm tall cylinders. These cylinders should be arranged in a circle just outside of the outer radius.
   *   A ring that connects each of these cylinders. The ring should lie along the bottom (or top, if mirrored) of the cylinder and the loop.

I'd like to make sure that I can adjust a couple of values for the brim, specifically an offset from the bottom (and top) of the main cylinder by 2mm, and the angle separation of the cylinders, and use step sizes to define the layout of the cylinders. I'd like the 'loop' of cylinders to be placed every 10 degrees, and a second loop every 5 degrees.

I think that's everything, let me know if you need more information. I'm hoping this will be a single `.scad` file, and I'd rather not need to include any external libraries.

Okay, I need a design for a mounting bracket for my Logitech Harmony Ultimate Hub (model O-R0004). I want something that will hold the hub securely and allow me to mount it to the side of a bookcase or other vertical surface using #6 wood screws.

The hub itself is roughly a rectangular prism with dimensions of 127mm x 105mm x 21mm. I'm picturing a bracket that has two "halves" that come together and grab onto the sides of the hub. Each half should have a band that goes around the side of the hub, and a support structure that attaches to the mounting surface.

I want the bands to be about 3mm thick and roughly 20mm wide, and extend a bit on the shorter dimension, maybe 10mm on either side. For the support arms, I'd like them to be sturdy. I am picturing a design where they have a chamfered profile to give them a bit more style and also to take less material without losing strength. I want the overall height of the support structure to be the same as the width of the mounting bands (20mm). Each half-bracket should have two screw holes for mounting to a surface. They should be countersunk for #6 wood screws, and we'll use a screw diameter of 3.6mm, a head diameter of 7mm, and a countersink depth of 1mm. I'd like a little bit of clearance around the screw holes too.

I want the design to be parametric so I can adjust the dimensions if needed. The key parameters will be the hub dimensions, screw dimensions, wall thickness, band width, and the overall holder height in the short direction. I'm comfortable using OpenSCAD, and I'd like to get a file with the parametric design.

I need a parametric OpenSCAD design for a remote control holder. It should have a slanted design, where the remotes are held at an angle, making them easy to grab. The holder needs to be customizable to fit different numbers of remotes, from 2 to 6, and each slot needs to have its own adjustable width and depth. I also need to be able to control the overall height of the front and back of the holder, as well as the angle of the slant. The design should also be printable, so I need to control the wall thickness. Finally, I'd like to use rounded corners for aesthetics and safety.

Here are some more specific requirements:

*   **Number of Remotes:** The design should be configurable for 2, 3, 4, 5, or 6 remotes.
*   **Remote Slots:** Each remote slot should have a customizable depth and width. Let's call the depths `depth_1`, `depth_2`, `depth_3`, `depth_4`, `depth_5`, and `depth_6` and the widths `width_1`, `width_2`, `width_3`, `width_4`, `width_5`, and `width_6`. If a slot isn't being used, its width and depth should be set to 0.
*   **Overall Height:** The holder should have different heights at the front and back. Let's call the front height `height_1` and the back height `height_2`.
*   **Slant Angle:**  I need to be able to control the angle of the slant, which I'll call `slant_angle`. It should be an angle from horizontal.
*   **Wall Thickness:**  The wall thickness should also be customizable; let's call it `t`.
*   **Rounded Corners:** I'd like the edges and corners of the holder to be rounded to a radius of `t`.
*   **Orientation:** The remotes should be stored standing upright, leaning against the angled wall.

I don't need any specific libraries, so feel free to use the built-in OpenSCAD features. I need all of the code in a single `.scad` file.

I'd like to create a customizable sign using OpenSCAD. I have some parameters I want to control, and I'll need some help getting started.

The sign should have an elliptical base, and I want to be able to control the radius and the height. I'd also like to have some text on the sign that I can customize – two lines, one for a general message and another for a name or company. Finally, I'd like to have the ability to add two "switches" to the sign that are essentially extruded rectangles. Each switch should have its own length, width, and depth parameters. All of these should be configurable through the Customizer UI. I don't need to see the code for any common libraries since I'm already using OpenSCAD.

For the base, let's aim for a general ellipse shape, with the following parameters:
*   `radius`: The horizontal radius of the outer ellipse.
*   `height`: The total height of the sign base.
*  `resolution`: Resolution of the curves used

For the text content:
*   `Message`: A customizable string for the first line of text.
*   `To`: A customizable string for the second line of text, to be displayed below the first line

And finally, for the switches:
*  `sw_split_len`: The length of the first switch.
* `sw_split_wid`: The width of the first switch.
*  `sw_split_dep`: The depth of the first switch.
* `sw_range_len`: The length of the second switch.
*  `sw_range_wid`: The width of the second switch.
*  `sw_range_dep`: The depth of the second switch.

I'm not concerned about the exact position of the switches or the text at this time; I can tweak that later.

Could you help me create an OpenSCAD file with these parameters exposed in the Customizer, and all of the above features implemented? I'm not sure the best way to get started, so I am looking forward to your help.

I'm looking to create a customizable USB charger spacer and ring in OpenSCAD, similar to what I've described before. I'd like to define several parameters to control the dimensions.

Specifically, I need:

*   A main spacer part with a frustum shape (a cylinder with different top and bottom diameters).
*   A hole through the center of the main part.
*   An optional cavity on the top face of the spacer.
*   A separate ring part that is designed to be placed around the spacer.
*   A cylindrical hole in the ring part.
*   A cavity in the ring part.
*   All parts should be customizable by using the following parameters:

    *   `bottom_diameter`: The diameter of the bottom of the main spacer.
    *   `top_diameter`: The diameter of the top of the main spacer.
    *   `hole_diameter`: The diameter of the hole through the main spacer.
    *   `height`: The total height of the main spacer.
    *   `cavity`: A boolean to enable or disable the cavity in the main spacer ("yes" or "no").
    *   `cavity_diameter`: The diameter of the main spacer cavity.
    *   `cavity_height`: The height of the main spacer cavity.
    *    `ring_height`: The height of the ring part.
    *   `ring_hole`: The diameter of the hole in the ring.
    *    `ring_cavity_diameter`: The diameter of the ring cavity.
     *   `ring_cavity_height`: The height of the ring cavity.
    *   `faces`: The number of faces to use for cylinders (for resolution).
*   I would like to be able to select if I only want to render the "distance" (spacer), only the "ring", or "both" the parts. The parts should be rendered separately (not merged).

Can you generate the OpenSCAD code for me? I'm not using any particular external libraries, just the standard OpenSCAD functionalities.

I've been having a really annoying problem with my over-ear headphones. They press on my glasses arms and cause a lot of discomfort, and it even makes my ears sore sometimes. I came across a design that looks like it would help, it's basically a little adapter that clips onto the glasses arms and then sits against the side of your head to take the pressure off your ears.

I'd like to have that design available as a customizable OpenSCAD file that I could use. The current design has a cylindrical portion that clips onto the glasses arm and then a flat, rectangular part that rests against the head. It has the following dimensions:

*   **inner\_diameter**: The inner diameter of the circle that clamps onto the glasses arm.
*   **outer\_diameter**: The outer diameter of the clamp circle.
*   **thickness\_facemount**: The thickness of the flat rectangle that rests against the head.
*   **height\_facemount**: The height of the flat rectangle.
*   **len\_facemount**: The length of the flat rectangle.

I need it to be parametric so I can adjust these values easily for different glasses. I'd also like to have the option to control the rendering detail with the `$fn` variable.

Could you generate the OpenSCAD code to create this? I think this would be a great solution for a lot of people. Also, since this is supposed to sit against the side of the head, it would be great if you could add a slight curve to that head-facing side of the rectangular pad. Maybe a variable `curve_radius` that I can adjust?

Thanks!

I'm looking to create a parametric RC barrier, similar to the one in the provided example, but I need it to be more flexible and easily customizable. The basic design is a linear extruded shape with angled supports, with a few added features for mounting.

Here's a breakdown of what I need:

1.  **Core Barrier Shape:** This is the main part, a flat shape that's extruded along its length. The shape is a polygon with points at `[17,0],[5,8],[-5,8],[-17,0]`. I need to be able to control the extrusion `length` as a parameter.

2.  **Angled Supports:** There are four angled support pieces on this main barrier. They look like cuboids, rotated and translated to the correct positions, on both sides of the barrier. The placement should be parametric, so ideally I should be able to adjust things like their distance from the main shape and angles. These are all the same shape, so hopefully you could define this once and just transform it. These need to overlap the barrier so there is solid adhesion between the parts.

3.  **Mounting Features:** There's a mounting system on the top and the bottom of the barrier. On each of these, there's a cylinder as a base with a slightly larger cylinder in a groove. This second cylinder is supposed to hold a nut and screw, and should be able to be controlled in dimensions. This would need to fit an M3 nut and a 5mm diameter screw. The upper cylinder should be smaller than the base cylinder, and there should be a gap between the two cylinders to account for the nut.

4. **Parametric Control**: The entire design needs to be parametric, so I can easily adjust:
    *   The overall `length` of the barrier.
    *   The size and position of the angled supports.
    *   The dimensions of the mounting system (cylinder diameters, length, and the gap).
    *   The size of the nut pocket, since this needs to be easily customized based on the nut to be used.
    *   The wall thickness should be variable and controllable via a parameter.

I'm not looking for an exact copy of the provided code, I'd like you to build it from the ground up. I’m thinking that it would be useful to define each section of the barrier as a separate module. I'm looking to have this built in a fully parametric way so that I can easily modify each part. I'm fine with multiple files, it’s nice to see the organization of the code.

I'd like to keep the file using standard OpenSCAD, I don’t need any libraries like MCAD or BOSL.

I'd like to design a customizable mounting bracket for GoPro cameras that attaches to aluminum extrusion profiles, specifically 2020 and 3030 profiles. I need a design that allows me to change parameters easily.

Here's what I'm looking for:

*   **Extrusion Profile Support:** The design should be adaptable to both 2020 and 3030 aluminum extrusion profiles. I want to be able to choose between these two sizes via a parameter.
*   **Mounting Options:** I want to be able to pick how it mounts to the extrusion. Specifically, the design needs to allow me to choose between the following:
    *   No T-slot engagement.
    *   A ridge that fits into the T-slot.
    *   A twist nut that is captured by the bracket and rotates into the T-slot.
    *   A twist nut that is captured by the bracket and rotates into the T-slot but 90 degrees different compared to the other twist nut option.
*   **GoPro Mount Height:** There should be a parameter to control how far the actual GoPro mounting point extends above the top of the bracket (the amount of vertical space between the top of the bracket and the base of the GoPro mount).
*   **Bracket Dimensions:** The bracket itself needs to be customizable. I need to control the width, thickness, and corner radius of the bracket via parameters.
*   **Mounting Hole Options:** The bracket should have mounting holes for attaching to the extrusion. I want to control the hole diameter and the distance between the holes. It would be awesome to pick the hole size from a list that includes M3, M4, M5, and M6.
*   **GoPro Nut Rotation:** It would be useful to be able to rotate the nut hole in the GoPro mount itself 90 degrees for mounting flexibility.

I don't have any code, so I'd need it generated.
I'm not using any libraries, so don't assume that I've included anything.

I'd like to design a parametric nose clip for a fabric face mask, to help keep glasses from fogging up. I need a design that can be easily customized to fit different nose shapes.

The clip needs a central curved section that rests on the bridge of the nose and extends out along the cheeks. The curve of this central part should be adjustable in both width and height.  I want parameters for the overall width (cheek-to-cheek), the overall height (from the bridge of the nose to a line connecting the ends), the width where the nose transitions to the cheeks, and the height of that transition point.

The clip should have small tabs that extend down along the sides of the nose where the mask is held in place, that is where it presses against the cheeks. These tabs should have a gap to accommodate the fabric of the mask, and should have rounded ends, and should have a small bump on the inside of the clip to hold the fabric in place.  I'll need parameters for the thickness of the fabric gap, the thickness of the base connecting the main body and the clips, the thickness of the clip itself, and the width of the band that sits on top of the mask.

The main curved section and clips should have rounded edges.

I will be using OpenSCAD and have access to the BOSL2 library. I would like the code to use the `BOSL2/std.scad`, `BOSL2/shapes2d.scad`, and `BOSL2/beziers.scad` files.

I think it would be useful to have a parameter for the smoothness of the curved section, controlling how many segments make up the curve.  I am also interested in having a parameter for band thickness. I'm anticipating band thickness being much thinner than base thickness to provide flexibility.

I need a parametric OpenSCAD design for a dripper holder that attaches to the rim of a water container, like a bucket. The holder should have multiple outlets for irrigation drippers.

Here are the key parameters I need to be able to adjust:

*   **`dripper_number`**: The number of dripper outlets around the circumference of the holder.
*   **`angle`**: The total arc angle the dripper outlets span. This allows for placing the outlets on only part of the container rim.
*   **`inner_diameter`**: The inner diameter of the ring that will sit on the bucket rim.
*  **`outer_diameter`**: The outer diameter of the ring. This controls the ring's thickness.
*   **`outer_clamp_height`**: The height of the outer lip of the ring which sits on top of the bucket.
*   **`thickness`**: The overall thickness of the ring material.
*   **`dripper_diameter`**: The diameter of the hole for the dripper.
*   **`dripper_box_heigth`**: The height of the rectangular part of the dripper box.
*   **`dripper_box_length`**: The length of the dripper box from the ring to the hose connection.
*   **`hose_diameter`**: The inner diameter of the hose connection.
*  **`resolution_big_features`**: Resolution for cylinder and similar shapes of the ring.
*  **`resolution_small_features`**: Resolution for cylinder and similar shapes of the dripper boxes.

The design should have a ring that clamps onto the rim of a bucket. The dripper outlets will be positioned around the ring, spaced evenly based on `dripper_number` and within the specified `angle`. The dripper outlets need to have a rectangular base that is connected to the ring. Additionally they need a cylindrical connection for the hose. The dripper hole should be oriented perpendicular to the radius, or as a tangent to the ring if `angle` is a full 360 degrees. Please ensure the code generates both the solid part and the cuts for the dripper outlets.

Could you generate the OpenSCAD files for this? I'm not using any special libraries, so just the standard OpenSCAD language features should be sufficient.
