Screwless gear cube/heart pin tool
by kcmelty, published
Inserting the pins into the center hub of the screwless gear cube and heart were kind of a pain in the fingers. This tool makes assembly much easier.
Use the end marked long for the long pins and the side marked short for the short pins. Very complicated I know.
Be sure to print it with enough infill to keep the pins from poking through the face at the end of the opening.
