M25 Endless Nut

M25 Endless Nut is a pointless fidget toy. The nut spins forever in either direction because it sits on a flat spot and doesn't touch the threads. There are two versions: tight, and loose. Both are included in the profile.The loose version has more play and the nut spins freely. The tight version has a little resistance. It's not hard to turn, but it feels more like a real nut/bolt.Both are fun but provide different types of experience. Assembly:Slide the nut onto the middle section of the bolt endAdd a drop of glue and push the narrow end into the hole of the main bolt
