# Print queue — 40 parts in build order

Generated by `scripts/print_queue.py` from the real STLs. Grams are a
planning estimate (solid volume × 1.24 g/cm³ PETG × 0.55 walls+infill
factor) — **the slicer's number wins**. Print the brim-baked files in
`cad/stl/brim/` and do NOT add a slicer brim on top.
