Screw, Bolt, Nuts and Washer Jig

thingiverse

I needed additional sizes (M10 and M12 to be precise) but wanted it still be compact. So i cut the lanyard ring, moved everything to the left and added the M12 size. The logic behind: if is too loose in M12 and doesn't fit M8 it's M10 ;) By doing that i gained a little length on both measuring markings and i added a small triangle on the side, where you can hook the inner diameter of a washer to measure it with the bolt scale. Hanging on the wall is still possible by using the M12 hole now :D
