Printable LM8UU bearing with PTFE inserts

This is a printable LM8UU equivalent bearing.
It is used in place of a conventional steel LM8UU.
I designed it so that it can be used as a replacement for Ultimaker style sintered-brass bushings.

This is also me trying to place a concept of using the easily available 4mm ptfe tube as bearing surfaces in Repraps.

Looking forward to suggestions and remixes!


This is also one of my first attempts at parametric design. There could be a lot of errors. Do point it out.
