MPCNC Drag Chain Remix

This is a remix of some thing created by other and some parts I created to adapt to the drag chain I downloaded.
To the pieces of the drag chain I have rounded some edges.
Starting from a piece of drag chain I made the initial piece to be fixed to the MPCNC base, and the final piece to attach to the XY-Carrier (https://www.thingiverse.com/thing:1272581).
Then I modified the Z-Carrier (https://www.thingiverse.com/thing:2354751) to adapt to my drag chain
