MP Mini Y Idler Fix

While adding the bigger bed, I had trouble getting new pulleys on the shafts that are fused to the Minis Case. Ended up breaking one off completely so I removed the other one as well. In the meantime I used bolts and nuts in the stepper mounts instead. While this does work, it adds side tension to the belt and after homing, the bed will move a bit. So I came up with this bracket. It has been working great for me so far.
