This is remixed from a model by Jori available here: https://www.printables.com/model/110363-sc8uu-replacement-for-igus-drylin-rj4jp-01-08-lm8u

The goal of this variation was to allow the 4 corner bolt holes to be used for mounting & assembly purposes, without interacting with the tension applied to the bearing.

My attempt here uses a single bolt to adjust preload on the bearing. That flexing piece moves independently.

I added a 6th bolt hole, in the middle of the other side, for symmetry.

I haven't used this yet, but it prints well enough with a small support in the middle (not included). I need to reprint it in PETG shortly, then I will share photos.
