Self-Aligning PLA Linear Bearings

Inspired by the IGUS igubal self-aligning flange bearings. I needed something to prototype with while I wait for the actual parts to arrive, so I printed these. Worked much better than anticipated.

These completely resolve any binding issues that are associated with mis-alignment.

If you want the actual part, they can be ordered directly from IGUS:
