Nut cracker

thingiverse

I designed this object from scratch, drawing inspiration from https://www.thingiverse.com/thing:3230634. I wanted to create something with humorous text on the side, so I printed the body on its back with supports and left the bolt as is. It's also a good idea to scale down the bolt by 1-2% to ensure plenty of tolerance between the two parts. This can be done by repeatedly scaling down until you notice at least a 0.5mm difference in size, which may vary depending on your printer settings.
