Same format as Lab Notes, different tense. Each entry below is something I am actively building — the spec it has to meet, what is working, and what is still unresolved. Entries graduate to Lab Notes once there is a finished lesson worth writing down.

Drawer Organizer: A Watertight STEP File Generated Straight From the Change Request
A 165 × 148 × 70 mm open-top drawer organizer with 60 elongated-diamond wall cutouts, modeled parametrically in CadQuery from a written spec — 19.5% less material than solid walls, validated against every dimension in the ticket.
Open: no test print yet. The geometry passes validation; whether 2 mm walls with this much perforation survive a real drawer is still unproven.
