Tronxy X3 Z Carriage Upgrade Remixed With Nema17 Mounts

UPDATE 18/12/2019: I did realized that the mount of the extruder is a little bit tight to some kind of extruders like the one I have: Drakon. To solve this, I have modified the part and give enough room to hold almost all kind of extruders we have. The old one is ok for bowden but if you use Drakon, you have to mofify the case to fit the mount, as you can see in the pictures. As a solution, I uploaded a new versión that has the mounting holes 12mm displaced from the old one... Hope this version
