A simple, lightweight, compact, and easy to print direct drive mount for Bondtech BMG, E3D V6/Volcano, and ABL setups. This mount is compatible with open carriage printers such as an Ender 3, Tevo Tornado, Alfawise U20.
This excellent design is originally made by Adolf_Muffin, but I made a couple of improvements:
M3 nut mounting holes and screws
Better BLTouch mount - the original was fragile and it would hit the tension belt adjuster at max X.
Better cable route on Carriage Mount -  moved the original cable route from the right to the left.
