Super long LM8UU linear bearing holder (90mm)

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:2783436.

This is a long bearing holder that can be mounted with four screws with standard spacing. It can take two bearings but only needs one set of mounting holes.

This should also ensure that two bearing are perfectly aligned with each other.

A quick remix of my own holder.
