This step by step tutorial will show you how to print, cut out, fold, and construct a gear to get you started building your own papercraft mechanical devices. There is still some small problems with the design, but I’m trying to balance ease of construction with functionality.
You will need:
1. A Laser Cutter or X-Acto Knife.
2. A T-Pin, Straight Pin, or Push Pin at least 5/8″ in depth, (regular pushpins are too short and map pins bend too easily).
3. Stiff paper, Brochures and Junkmail like Restaurant Menus are a good choice as long as they fit into whatever printer you’re using.
4. A half hour of time and Patience, this is very much like miniature model building.
