Tin can cigarette butt collector
A 3D-printed adapter that turns a tin can into an outdoor cigarette butt bin. Butts fall into the metal can, keeping embers off the plastic.

Limitations
The fit coupons, the per-hen cap plates (the 2026-10-04 four-cap test plate was accepted on 2026-10-12) and a body with the 25°-turned lugs (2026-10-12) have been printed. The complete sealed enclosure, the O-ring seal, water resistance and the harness tabs under load are untested, and no hen has worn one. No conductive or carbon-fibre filament: it detunes the antenna and can cause a short.
