The Print Files

3D Print Files

Every 3D-printed part on the cart, as zipped binary STLs — click to download, unzip, slice, print. PETG unless a part's build-guide entry says otherwise; print settings and orientation notes are in §16 of the build guide. Updated 2026-07-23; files are regenerated from the Python part generators whenever a part is revised.
