Simple Machines: Cardboard Mechanical Automata/Karakuri

thingiverse

This source file presents plans to create mechanical boxes from cardboard and wood. Designed as an educational tool, it teaches children basic building techniques and introduces them to simple machines. The project is suitable for ages 3-13, with past results showcased in the provided video. If you're a teacher interested in implementing this project, contact the creator. The boxes are crafted from thick cardboard, preferably recycled bicycle boxes, while gears, cams, and cranks are cut from wood. The design accommodates 3/8" dowels, but ensure proper fit before cutting wooden parts. To assemble, first score the cardboard folds using the "First Cut" tab, then cut through with the "Second Cut" tab. For wood parts, refer to the labeled tab for crank, gear, and cam pieces, which are typically cut in 5mm plywood.
