Helical Linear Bearing LM8UU Replacement

Helical Linear Bearing LM8UU Replacement

Description

This is a printable, helical linear bearing, replacement for the stock LM8UU found on many printers including the Anet A8, and an alternative to Igus Drylins. Although I've taken inspiration from many other designs, this is an original design not a remix. Once installed and worn in, they should be smoother, quieter, and wear the guide rails less than the stock LM8UU bearings. This is not an easy print, so please pay close attention to the following sections. I've designed a carrier for these bearings, the stl file is included here, or you can get it from: https://www.thingiverse.com/thing:3119275
