We Built the Testing Framework CAD Never Had
CAD Harness: open-source automated testing for STEP assemblies. Caught 53 interferences, reduced STEP from 70MB to 13MB. Replaces $7,500/year enterprise tools with 500 lines of Python.
Development notes, design decisions, and build logs for M3-CRETE. Written by Nick Sonnentag as the machine comes together. Source files, BOM, and CAD live on GitHub.
