AM6 Z-Motor-Holder - Upper Z-Rod-Holder

I redesigned the Z-Motor-parts, because the original ones did not fit correctly. I redesigned the upper parts also, so you can take out the lead screws without having to disassembling the holder. The original part with Bearing did not print properly.

The original parts are from here: https://www.thingiverse.com/thing:2394506
