Ultra Lightweight All in one 8mm Bearing and Mount

thingiverse

This is my take on an ultralight LM8UU bearing and mount replacement for the Wanhao Duplicator I3's and its clones like my Maker Select V2.1. Its crazy light weight, very strong, requires no nuts, and weighs only 5g vs the stock 26g bearing and mount.

I've found that even slight misalignment can cause major issues with this bearing due to its length. It will be tight on your 8mm rod. To get it working smoothly, I used a torch to heat up the 8mm rod and then carefully slid the carriage back and forth on the rod until it moved with ease. When tightening the screws that mount the bearing, go easy as excessive torque can twist off the nut-less mounts. It's also crucial to tighten the bearings one at a time while aligning them to the rods, sliding the carriage in between screws to ensure the last screw doesn't bind everything up. I'm working on printing out solutions to these issues but for now it takes some tinkering to get them working well, and once you do they're great!
