E3D V6 hotend with BLTouch for Linear guide and 2020 Extrusion

This assembly is an E3D V6 hotend with BLTouch, direct drive, and a standard blower fan mount with duct.

This mounts directly to an MGN12 linear rail/guide block, which is mounted to a 2020 extrusion.

The orientation of the X-axis drive motor should be vertical shaft with the belt running equatorial through the extrusion gap.

The assembly has a belt clamping mechanism on the bottom.

Some useful features of the assembly:

- Complete isolation of the E3D V6 heatbrake cooler with an upward air deflection

- 40mm fan mounting for the heatbrake cooler (Noctua for silence)

- BLTouch mounting behind part cooling fan duct

- Part cooling fan duct has a mounting point to the main body

- Both part cooling blower fan and duct have a 2mm mounting gap to add a rubber washer for less noise (can see it in the .3mf files)

- The extruder is part of the main body to add rigidity

- Nearly all of the mounting holes have a captive nut

Things you may need to complete this assembly:

Parts:

Nema 17 stepper motor

E3D V6 or V6 clone/J-head

BLTouch (optional)

5015 blower fan (the most common, I recommend ball bearing type)

40mm fan (Noctua recommended)

Hardware:

- Various lengths of M3 and M4 hardware in button and socket head fasteners with nuts

(it's good to have lengths from 8-25mm on hand)

- 694 (RS, Z, or ZZ) ball bearing for the extruder idler

- MK7 extruder drive gear

- M3 and M4 rubber washers

- short length of PTFE tube

- M6 pneumatic fitting (optional)
