Anet Evolution X Carriage Connector (adjusted spacing)

(Remixed from https://www.thingiverse.com/thing:2786292)

The hole spacing on the Anet Evolution X carriage didn't match my metal carriage bracket from my Alunar M505 (Anet A8 clone), so I remixed from the Fusion 360 file to match my hole spacing (38 mm x 11 mm).

Also reduced the size of the side holes for the brass inserts to adjust the belt tension, as they are under considerable tension when the belt is tightened and hold onto the insert better if they are more snug.
