I wanted to reuse the original LM10UU bearings from the MK4S on the Core One and designed this bearing mount.  The outer dimensions are identical to the mounted bearings that came on the Core One with the exception of the clamping tab. The same part is used on either side, and mounted with the tab down.

Printed end down on the bed in PETG, 0.2mm layer height, 25% Gyroid infill.  Printing end down will result in a part that clamps better.

Bearings are slide into the mount until the machined ring on either end of the bearing is aligned with the edge of the mount (aka, centered).  Use two M3x10 cap head screws to clamp the bearing in place.  Do not over torque - the clamp edges do not close.
