Parametric Projects

A collection of parametric CAD designs and 3D printable models, primarily built with OpenSCAD.

Philosophy

Parametric design enables customizable, reproducible, and maintainable models. Rather than static STL files, these projects are defined by code with configurable parameters—making it easy to adapt designs for different sizes, materials, or use cases.

Development Environment

Tools

• OpenSCAD 2025.03.16 - Primary CAD software
• BOSL2 2.0.716 - OpenSCAD library for advanced features
• Round-Anything - Filleting and rounding utilities

Library Verification

Before starting work, verify libraries are accessible:

# Generate and run the library test file
python3 docs/skills/openscad-library-check/scripts/create_library_test.py
open ~/Documents/OpenSCAD/library-test.scad

Press F5 in OpenSCAD to confirm BOSL2 and Round-Anything load correctly.

See the OpenSCAD Library Check Skill for troubleshooting common library issues.

Skills & Documentation

The docs/skills/ directory contains reusable knowledge and troubleshooting guides:

• OpenSCAD Library Check - Verify BOSL2 and Round-Anything installation, troubleshoot common issues, best practices for spiral generation and geometry

Design Principles

1. Parametric First - All dimensions should be variables, not magic numbers
2. Documented Parameters - Include comments explaining what each parameter controls
3. Printability - Designs should be printable without supports when possible
4. Modularity - Break complex designs into reusable modules
5. Version Control - Commit working versions before major changes

Printing Notes

General Settings

• Printer: [Your printer model]
• Slicer: [Your slicer]
• Typical Settings: 0.2mm layer height, 20% infill

Material-Specific Notes

• PLA: Easy printing, good for prototypes
• PETG: Better strength and temperature resistance
• ABS: Requires enclosure, best mechanical properties

Contributing

This is a personal repository, but design ideas and improvements are welcome through issues.
