Prusa i3 MK3 * Y-Axis Polymer Bushings/Bearings

thingiverse

I'm not too fond of the U-bolt mount for the Y-axis bearings. One of my bearings started making some noticeable click sounds, so I decided to give polymer bushings a try. The number at the end of each STL filename and engraved into the body indicates the clearance of the bore in increments of 0.1mm. For example, "MK3_spiral_Y_4.stl" has an inner diameter of 8.4mm. In my case, I found that No. 2 worked best.
