This is my version of a direct drive setup for the Ender 3, CR10, CR10S, CR10S4 and CR10S5  using a BMG extruder and E3D V6 hotend. I designed this with the intention of the BMG extruder being coupled directly to the E3D V6 hotend without a piece of PTFE bridging the gap. I also wanted a setup that allowed easy access to the BMG extruder and kept a minimal footprint.
This is not designed to work with the stock hotend or a Micro Swiss style hotend.This design also uses the stock cooling fan found on the E3D V6 to keep the overall profile small.
The part cooling fan comes in 2 styles. One is designed to fit a 3mm x 5.5mm knurled nut insert. The other uses a nut pocket for a 3mm hex nut. The part cooling fan fits a 5015 blower and shares 1 mounting screw with the BMG extruder. The part cooling fan is just a basic design for testing out the mount. Expect future design revisions to the fan duct.
The mounting plate supports a 18mm inductive probe. Probe is held in place by a single 3mm set screw. Mounting plate attaches…

UPDATES:  
I've updated the BASE_E3D and BASE_Volcano files since I got some feedback that some versions (different clones have slightly different dimensions) of the BMG don't fit into the mount. Also, you can adjust the Z position of the BMG now - can also be used to fine tune the Z position of the nozzle.
UPDATES:  
I've update the body and fanduct to fit on a volcano hotend (files base_volcano.stl and fanduct_volcano.stl). I haven't tried to assemble it for a volcano hotend, but it was told to me it fits. Please leave a comment, if there's any troubles.
OVERVIEW
This is an ALL METAL DIRECT DRIVE for the E3D v6 and BMG extruder (FULL DIRECT DRIVE, NO BOWDEN NEEDED!) for the standard carrier found at TEVO, CREALITY, and many other printers. I've tested it only on a TEVO Tornado, but I assume it should fit on any printer with the same carrier - see attached photo (CR10, Ender 3,...).
The following guidelines were considered when designing this extruder mount:
it should be a full all metal direct drive (with no…
