Bruder 320 conversion with 3d printed parts

yeah I would imagine you would have to machine everything just like you would with metal. I would think doing a acetone smoothing that would create almost a hardened shell around the outside of a abs part and then machine that. Everytime I try to get a good finish on this thermoplastic it ends up melting and I havent been able to get a real good surface finish, but I havent invested too much time trying either.

Here are some pics of a couple of the cylinders I made. 1 of the three I made is perfectly leak free, the other two ....not so much! Nothing horrible but they are dripping around the gland where the shaft leaves the end of the cylinder. It looks like I need to re invent my seals somehow. It was pretty neat to see them moving though, and even with the pump just barely turning they are quite powerful.
