This is just a model i made for fun, but if you want to print it yourself, the shaft, handle, and housing are printed together with supports, and everything else just snaps in. You will also need 3 rods and 3 pistons to make it right. The model has been updated since the photos, so don't be fooled by how it looks different. The rods were too thick so that they were rubbing against the sides, so that it was not consistent, so I made them thinner in a different file.
