Y axis Pulley mount Prusa i3- Aluminum frames (Max MIcron and others)

Added 3mm lift, toothed idler mount - smaller footprint too • Note: A 3mm lifted version exists that raises the bearing 3mm to achieve a better belt line. Broken 2 stock y mounts for the Max Micron, the first was poorly printed due to thin walls, and the second failed due to over-tightening the pulley holding nut, which cracked the support. The design should be stronger than it is. To address this issue, I created a new mount that's significantly more robust. It features rounded edges instead of sharp corners to reduce stress concentrations. The pulley bolt/nut is designed for stock M3 size. The nut is recessed and secured in place without requiring any additional tools on that side. However, it does fit tightly, so you'll likely need to mount the nut at the very end of the screw, then push it into place from behind before removing the screw and assembling everything. Frame mount screws are standard M5's with a washer.
