Ploopy Adept with BTUs

This is a mod of the Ploopy Adept trackball using BTU bearings.The BTUs used are Bosch Rexroth R053010810. This only includes the top part of the trackball, as the rest is unmodified and can be found on the official Ploopy Adept website, along with the electronics that are needed for the trackball and further instructions. I recommend to print using a layer height of 0.2mm.
