The hydraulic system was relatively easy to build. It consists of only cylinder meshes and spheres, that I positioned, scaled and then joint together.

I first attempted to build the upper joint of the pistons like this, but quickly decided that this would use up to much time, because I’d still have to built a screw that this joint can turn around. Hence I decided to simply use a cylinder and put a screw on it with the help of texture.

Just for the sake of accuracy I cut out a concave shape out of the lower magnetic ball joint, so that the ball could move freely. I did this by using a sphere and a boolean operation on a cylinder.
