Source files

Every editable file of this project in one place. Edit it, test it, and send the changes back.

Download all 146 files as one ZIP (1.2 MB)

The ZIP keeps the repository folder layout, so it unzips straight over a clone. It leaves out the generated bulk (3D explorer data and preview STL meshes), which the generators rebuild.

How to edit

1. Change a number, not a drawing. The SVG files and the 3D explorer are generated. Change the parameter in generators/ (or at the top of the .scad file), then run python projects/welcome-space/generators/build.py.
2. Print STLs come from the SCAD files. After every .scad change run bash scripts/export_stl.sh.
3. Record what you measured in a Test result issue and in the assumptions log.

Send it back for the final optimization

Attach to your message: the ZIP, your filled test CSVs (tests/*.csv), the issue numbers of the test results and the decision (Model A or B). Say which parameters you changed.
