Custom Knex Parts
grabcad
I made a few custom 3D printable K'nex parts. All have been printed and work great. Feel free to contribute to this project with other custom pieces. Parts: Custom size one to one gear Pair of two to one ratio gears Rack (works like a blue gear) Worm (also works like a blue gear) 3D printing: All parts can be printed without supports, I have been using 20% infill, seems to be enough. Post Printing: Drill large holes with 1/4" drill bit, drill keyholes with 5/32" bit The gear tooth edges may be a little bit sharp, you may want to sand them down
