Hypercube Revolution Z axis holder

After 250 hours of printing my z axis bearings began to slip out of the holders.

Thinking it was a simple task I designed a dual bearing holder that was still split in the center like the original and released it without testing first. When I installed the bearing holder I discovered that the bearings were working but not perfectly aligned. It also had the problem of the linear rods covering screws I wanted to adjust. I needed some slight play in the adjustments for the bearing to slide freel
