A simple, lightweight, compact, and easy to print direct drive mount for Bondtech BMG, E3D V6/Volcano, and BLTouch setups. This is compatible with open carriage printers such as an Ender 3 (Pro/V2), Tevo Tornado, Alfawise U20, etc.
This excellent design is originally made by Adolf_Muffin, but I made a couple of improvements: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.

TESTED ON: TEVO Tornado , feel free to modify for your printer (there is a .step file attached)
Use the 2.6mm version of the base for carrier plates that are approx. 2.6mm thick and the 3.1mm version for thicker carrier plates (the 2.6mm version is apparently a little too loose, I'll try to fix that within a few days). Please write in the comments if anything is too loose or to tight, also, please specify which printer you are using and the thickness of your carrier plate.
I've only updated the E3Dv6 version. The version for the Volcano hotend will follow shortly. I've taken the previous version…
