Ender 3 Direct Drive - BMG + E3D V6 + BLTouch

1.5.2022: Just note - this design is obsolete, better version in all ways is here

I was not satisfy with the original solution, so I tried to modify it as follow:

- BLTouch support in front of the body (I didn't want to block air flow from the side cooler). - Duct is closer to the nozzle and flows more accurately. - Duct is higher so it doesn't cover view to the nozzle and also doesn't accidentally "touch" paper clip which I use as glass holder. Duct, BLtouch holder, 5015 FAN holder use M3 DIN934 nuts and M3 screws.

Rev. 3 @16.1.2021

Cable holder added

Rev. 2 @ 6.1.2021

Few small modification in the source files.

BLTouch offset: -27,2mm in X; -31,4 mm in Y. Z axis is up to you (please follow manufacturer instruction).

Rev. 1

Both body parts are screwed together by two M3x22 DIN912 screws and M3 nuts (see attached picture).

Thanks to @Kiron and also @Leovade
