608 Bearing Keychain
thingiverse
Simple key ring trinket for those spare 608 bearings collecting dust. Requires 2 3mm flat-head screws, about 10-15.5mm long (12mm ideal). Internal threads are in the print, so printed 3mm screws might work (I haven't tried it). Also the end for the key ring will need to use a small diameter ring (I'm using 15mm). The one pictured on my keys is embossed with my company letters. Add your embossing using your favorite STL editor.
