Description

For those who have upgraded their Prusa MINI to Dual Z using that mod: 
https://www.printables.com/model/311911-prusa-mini-dual-z-ck3d-mod

I made a quick system to attach the PSU (new version) to the second Z profile.

A FEW POINTS:
- It may not be the most elegant way of doing it, but it works :-)
- Works with M5 T-nuts and M5x12 bolts 
- I made it so the height is adjustable AND there is a foot to stick a pad at the bottom, for more overall stability
→ Because of the foot, the model is very long and DOES NOT PRINT on a mini unfortunately. You need a MK3 or 4, and print in diagonal. Feel free to modify the model to allow printing on MINI.
– Inserting the PSU requires a bit of strength because the model is very tight, but once the PSU is in, it doesn't move.

I also made a small cable management box that goes onto the original Z axis. This is where I hide the mess created with the Z motors rewiring. Nothing fancy, it just works. You'll need 2 M5 Tnut / bolt, and 2 M3 bolts to attach the lid. No nut for the lid, the bolts just eat the plastic behind
