Root 3 CNC Z-Axis Bearing Cup Plug

This part is an optional/unofficial add-on part to the Root 3 CNC project(https://www.thingiverse.com/thing:1750276). The Z-Axis linear guide has two parts, "Z-Axis Bearing Cup Top", and "Z-Axis Bearing Cup" bottom which receive 608zz skate bearings. Depending on the print material, the skate bearings can be a bit loose. This part is meant to snap in to the cups to help keep the bearings in place. You may need to scale the part up or down a few percent, depending on the materials/bearings in
