Miniture Piston Keychain has been modeled to have very low clean up required by adding supports & radii. I also separated the bigend to aid printing plus I think the little bolts give it a cool mechanical feel.Parts Required:1) 2x M3 x 10mm socket head cap screws.2) 2x M3 nuts.All should be available from a hardware store
