LM8LUU Lineer Bearing Z axis

These were designed for the Z-Axis, But can be Scaled down on height to 15mm for the Y and X axis, there may be some slop, but no more than ones you would buy. The reason for the Different sizes of the hole for the axis is because depending on your printer or your rods the standard opening sizes was too small for mine so I put others in there so you can use what is best for you. Printed with PLA, but Nylon would work as well, for best results for end product, use a bit of PTFE super lube on the bearings, been printing on mine for 2 months and about 4 spools of filament with no problems, they ride smoother than stock bearings and save you money since you don't need to buy them at $25.
