Bruder 320 conversion with 3d printed parts

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.
