graves facetting hand piece

thingiverse

I bought a graves mark IV facetting machine only to find out it wasn't accurate and upon inspecting every part found shims around the bearings that this part goes on. it was shimmed from the factory due to a bad casting and machining of this part as you cant get this part from them cheaply or guarantee it wont be just as bad, I decided to just make my own using my 3d printer and this is it after 4 tries i got it working perfectly.
