Toybox Alpha parts
147 PLA models for the Toybox Alpha and Alpha Three, including a pocket Staunton chess set and board, checkers, dice, and holders for cards, cables, and a phone. Each file already sits on the bed. The printer envelope is 75 × 80 × 90 mm, and every part stays inside the shorter 74 mm axis so a turn in the app still fits.
PLA, 0.4 mm nozzle, about 0.2 mm layers, no heated bed, no supports. Slots and holes under about 2 mm are left out on purpose: this nozzle will not hold them open. Kitchen parts do not touch food. Nothing here is a car-seat, helmet, or medical part. These models have not been bench-printed on a Toybox. Measure the first part, then scale in the app if a bore is off. The spool axle is 18 mm inside and 32 mm outside because the hanger diameter is not published.
