Spool holder for K8200

I upgrade to a 2nd z axis. No space for the original spool holder so I made this holder. The plan is to make it possible to change the top part and add different. I upload more parts soon.
If the parts do not fit, you have to sand down the parts.

Update: I add a new one, I use the old parts and bearings.

Update: I add a extender it's for spools with a diameter over 20cm.
