A workshop at my former place of employment included a handy pegboard rack for hanging tools upon, but what to do with all those holes not occupied by hooks? Time for a DIY answer to a decades-old craze!
Made with no traditional 3D-modelling software; just two helper disks created and scaled in MakerWare.
"Lite-Brite" is owned by Hasbro, not me. This toy is nothing to do with them, really.
This file produces pegs sized nicely for our pegboard, which has holes around 6mm in diameter. Scale them to fit your own!
Works best in translucent PLA colors, many bonus points if you can somehow get a safe light source behind your pegboard.
