Velleman K8200 Z motor design with pillow block mount

I liked the design (https://www.thingiverse.com/thing:1685126) by Charlies3DT but i added the option to mount a P08 pillow block to the top mount for added stability. I don't like my spindles floating in space...
You can use M4 nuts and bolts but you have to press the nuts in, or use a soldering iron.
