Cap for design chairs

thingiverse

A friend of mine had bought design kitchen chairs, metal with little caps on the top and bottom. The caps were broke and the manufacturer did not make them anymore. So I revers engineered the cap and it works fine, he replaced all the caps with these printed ones and it works fine even on the wooden floor. I used ABS and max infill to make it solid and very strong. It does not need any print support.
