A simple small tool to open bike chains.
Additional parts needed:
-a vice or a strong clamp (maybe a hammer could work aswell)
-a m3x2 bolt or even better a 3mm steel nail
-two m6 nuts
The nuts and the nail/bolt will take all the forces while the 3D printed part will hold everything in place. Just make sure that everything is aligned properly because the bike chain will take quite some pressure before the bolt from the chain will get loose.
In the design you have the possibility to add an overhang that can be directly attached to the vice and adjust a few simple parameters
