Custom letters, numbers & name tags (OpenSCAD)

A fully parametric OpenSCAD name tag generator, designed as a reusable tool rather than a static STL.

The primary use case is clean, reliable name tags, but the same code can also generate individual letters, numbers, and custom text-based tags using different parameters and print profiles.

This model is built with a strong focus on:

• consistent geometry
• print reliability
• clean edges and rounded 3D surfaces
• flexibility across multiple use cases

Key features

• Original parametric OpenSCAD design
• Generates name tags, letters, and numbers from a single codebase
• Optimized for 0.4 mm nozzle
• No supports required
• Easy to scale and customize
• Suitable for single-color and multi-color printing

Included print profiles demonstrate:

• uppercase letters
• lowercase letters
• numbers
• example name tags

Parameters explained (OpenSCAD)

Text

• name
  Text to generate (name, word, single letter, or number).
• text_size
  Controls overall text size.
• text_offset_x, text_offset_y
  Fine optical centering of the text.

Tag dimensions

• tag_height
  Overall thickness of the tag.
• padding_x, padding_y
  Spacing between text and tag edges.

Print style

• print_style
  • "simple" → cut-through text (single-color print)
  • "multicolor" → inset text for multi-color printing

Note:
Cut-through text works best for letters without enclosed shapes (e.g. E, L, M, S). Letters like A, O, R will lose inner islands in simple mode.

Magnets / holes

• use_magnets
  Enables magnet pockets or hanging holes.
• magnet_diameter
  Diameter of magnet or hole.
• magnet_clearance
  Extra tolerance for easier fit.
• magnet_inset_height
  • < tag_height → magnet pocket
  • ≥ tag_height → through-hole for hanging

Export mode

• export_part
  • "tag" → exports the full name tag
  • "text" → exports text only (letters or numbers)

This parameter is essential for multi-color printing.

How to print

Option 1: Simple (single-color)

Fast and minimal setup.

Set:

1. print_style = "simple";
2. export_part = "tag";
3. Export one STL
4. Slice and print normally

✔ One filament
✔ Quick prints

Option 2: Multicolor (recommended)

Clean, professional result with inset letters.

Step 1: Export two STL files

• Tag body
•  print_style = "multicolor";
•  export_part = "tag";
• Text only
•  print_style = "multicolor";
•  export_part = "text";

You will get:

• one STL for the tag
• one STL for the text

Step 2: Combine in Bambu Studio

1. Import both STL files simultaneously into BambuStudio

2. Click “Yes” to “Load these files as a single object with multiple parts?”
3. Assign different filaments to:
   • tag body
   • text
4. Slice and print

✔ Perfect alignment
✔ Clean inset letters
✔ No manual painting

Design notes

• This is an original parametric generator
• Presets and print profiles are provided as examples of use
• The same code can be reused for many text-based applications
• This generator is meant to be reused, adapted, and extended for many future projects.
