Ender 3 BMG E3D V6 Direct Drive Extruder Lightweight Mount
Updates:
2020-12-31 - Redesigned fan shroud and zip tie mounts. I removed the gantry clip because it provided no benefit to stability or wiring. Fan shroud mount should now only require supports on the extreme end with the screw hole. I have included a screen shot of how I have support blockers configured in my slicer.
NB. The previous versions had a mistake in the fan shroud position.

2020-12-29 - Added support for Slice Engineering Mosquito hotend. The back plate was thickened, the fan shroud was lowered 0.5mm. The hotend wiring and filament runout sensor was relocated to the front of the gantry.

Receiving screw holes are sized to be tapped using an appropriate M3 bit, but will hold a M3 screw if filed or drilled out to the right size.
The fan shroud is a modified part from the Prusa i3 MK3S, and can be substituted with the original Prusa part (with appropriate Square M3 Nut).
When using the Mosquito Groovemount adapter, the upper and lower parts are split to allow for printing without supports.
