Summary

I upgraded my y-axis to a single linear rail setup and noticed that the belt was slightly rubbing against the rail. After looking at increasing the bearing size which would require a custom belt size, I decided to simply move the mount point up 2mm on the housing. This keep the belt free and clear from the rail with no need for new bearings or custom belts.

There are two versions, one that is enclosed and one that is open to reveal the bearing mechanism

Added an enclosed version with the mount point in the original location
