Files

File	Purpose
maker-chip.scad	Main model. Open in OpenSCAD.
qr.scad	scadqr dependency, included by the main file.

Orbitron-VariableFont_wght.ttf	Font used for the text on the front face.

Usage

1. Install OpenSCAD (2021.01 or newer).
2. Install the Orbitron font, or change text_font in the .scad file.
3. Open maker-chip.scad and tweak the parameters at the top:
   • qr_text — what the QR encodes (set to "" to disable)
   • text_top / text_bottom — front-face text
   • logo_file — swap in your own SVG (closed paths work best)
   • disc_color / spot_color / logo_color / text_color / qr_color
4. Render (F6) and export to 3MF for a multi-material slicer, or STL for single-color printing.
