Robo 3d R1 threaded rod stabilizer

This is stabilizer I made for my Robo 3d R1. I have the Z rods that go to the top of the case, so if you don't have that model these may not work without other mods.

The large hole fits a standard size skateboard bearing (608 size). The small hole is 8mm in diameter. All pieces are press fit, so some fitting may be needed after printing.
