My friends father was putting together a vintage 60s/70s ATI pool table and all the rail caps were breaking as the plastic had degraded and was extremely brittle. None of the models I found came close to fitting and the only place that sold replacement parts was out of stock.

So I used this as an excuse to increase my Onshape knowledge with the help of the onshape community discord. Overall they came out pretty well, not perfect but more than functional and he's happy that the corners and edges of the rails are protected.
