Prusa mini anti z wobble

thingiverse

As a result of massive z banding, I designed this simple anti z wobble. *Requires:* - 2 x m3 screws - 10mm to 16mm will work. - 1 x ball bearing 8mm x 22mm x 7mm. You can freely change the model to fit any ball bearing that has an inner diameter of 8mm, which will fit the z rod. It did clean up my z banding a bit, but I'm not sure it's really needed :) Img shows first edition - I wanted the screws hidden, but it is way easier to screw in from the front. *How-to:* 0. Place the x carriage about halfway up. 1. The cable for the z motor needs to be loose. 2. Unscrew the z motor - 2 screws on the sides. 3. Lift up the z motor and rod 1-2cm. 4. Slide in the bearing under the rod, and push it up a few cm. 5. Re-attach the z motor. 6. Lift the bearing and add the two brackets. 7. Place the whole mount at the bottom, before finally tightening the screws.
