Piston Fidget

Print in place, fidget toy of an engine piston! Great to fiddle back and forwards with, and the connecting rod bearing hole makes for an excellent keychain attachment point. Great as a gift for your favourite mechanic, or just something to noodle about with in your pocket. The shaft bridges reasonably well without support, but you get that little bit of extra cleanness with support, so I've left the support on my uploaded print profile.
