Bearing mounts for Y Axis idler pulleys
thingiverse
Based on chuckmurray's "Overkill" bracket. Fits 2 5mm ID/16mm OD ball bearings in each bracket (RS Part 625-2RS: https://au.rs-online.com/web/p/ball-bearings/6189878/). Works fine with stock M5 bolts and prints without support. My SD3 has a printed mount for the left Y Axis rod so the bottom lip is slightly thinner on the left block - I'm not sure if this is the case with all Solidoodles. Either way, it shouldn't pose a problem if yours doesn't. Instructions You may need to smooth out the inside of the hole with a file or rotary tool - you should get a nice snug press fit for the bearing. Other than that, you should be able to reinstall the new blocks in the same manner as the originals.
