Y Belt Rubbing Solutions

[printbus]

I recently printed a pair of the Y-idler belt guides and installed them today. In addition to putting one on the Y-idler, I also put one on the X-idler. I think these are perfect for the job. I used a total of three M5 washers, one as a spacer between the two bearings and then one outside each bearing. The washers on the outside of the bearings provide just enough clearance for the pulley sidewalls. On the X-idler, I swapped out the MakerFarm wood "washer" for the same three washer approach and an M5 Nyloc nut.

Two cautionary notes - you'd want to make sure the teeth of the pulley print clean to minimize "noise" in your prints, and you may have to extend the length of the belts some to accommodate the increase in diameter of the pulleys.

These are definitely something every i3v should have, if nothing else just to improve the design quality of the machine.
