XYZ Da Vinci Extruder Repair Parts

I designed a replacement bracket for the aluminum wheel failure that occurs on the Da Vinci. I wanted something that was a direct replacement so I designed around a MR137ZZ bearing.... something close to the diameter of the aluminum wheel.

EDIT (2/3/19): I recently redesigned the bracket I originally posted. I went with using two bearings on the peg and it helped a lot. It's currently printing a mausoleum piece that I would never have trusted on this machine. Close to 8 hours and no issues. I have already printed two smaller items, but I wanted to see if it would go the distance. The second part with the cylinder is because my first test of this tapered the bearing area, so it didn't hold the second bearing.

EDIT (2/10/19): I had successful prints with version 2, but noticed flexing with both it and the metal plate that might have contributed to the filament stopping mid-print. I added another screw location that aligns to the motor mount. Additional prints turned out fine. Fearless girl (in purple) and some tracks.
