Revolver Barrel Pen Holder
thingiverse
Small entertaining project that I attempted. The design has some flaws but it works as expected. You´ll need 2x 608z bearings. It consists of 3 3d printed parts and the bearings. The pictures are self explanatory on how to assemble it. I printed in a very poor quality PLA and it came out pretty nice (except for the puke like colour). It can be 1000x better if you print in a silver, grey or pewter filament. Other than that I like it a lot, and it is functional.
