Development

The model is plain OpenSCAD with no library dependencies:

• dynamometer_dimensions.scad: parameters and structural assertions.
• dynamometer_parts.scad: the printable parts.
• dynamometer_assembly.scad: preview and export entry point.
• crimpdeq_reference.scad: a simplified snapshot of the Crimpdeq case (crimpdeq-case v2.0.0) used for fit and collision checks.

All dimensions are in millimetres. Override parameters with -D name=value; unsafe combinations fail with an assertion.

Preview and export

openscad dynamometer_assembly.scad    # preview; options in Window → Customizer
bash export-parts.sh                  # every part as STL into exports/
python3 export-bambu-project.py       # Bambu Studio project into exports/

Validate

Run after every geometry or dimension change:

CHECK_JOBS=4 OPENSCAD_RENDER_FN=24 bash check-collisions.sh

It checks the parts for collisions and required contacts, confirms that each exported STL has the expected number of bodies, and that unsafe parameters are rejected. check-real-case.sh runs the same fit checks against the real crimpdeq-case source. CI runs both on every pull request.

Book

The images in docs/src/images/ are rendered from the model; re-render them after geometry changes and preview the book:
