2018-04-02 - Updated Version: I quickly realised a few problems with the first design and have since updated the following:

  1. Filament Feed Alignment
  2. Spring Tension Placement - old version caused the finger the wander out of alignment
  3. Stronger Frame

New version has been working better than expected, so much so I might upgrade the printer further with a heat bed.

For those, like me, that still have an old cubify cube gen 2 lying around, here is an upgrade to to get rid of the default print head assembly and replace it with a E3D V6 setup.

This upgrade came after I destroyed the old main board on purpose and replaced it with a TEVO TARANTULA MOTHERBOARD MKS BASE V1.4 since it can handle a 24V supply.

This is designed to re-use the existing stepper with the drive gear fitted in place.
The overall design would be better with a new stepper motor, as the gear is a little close to the stepper.

What you will need

  1. E3D V6 Hotend Assembly
  2. One stiff spring. I used the springs that came with the bed leveling kits
  3. 3x M3 30mm bolts
  4. 4x M3 20mm bolts
  5. 7x M3 nuts
  6. one U -Groove ball bearing and appropriate screw to keep in place

EDIT: Old parts list, just get a few M3 40mm bolts,nuts and washers. That and one M4 40mm bolt, nut and washer for the spring at the rear of the finger. And one M4 20mm Hex Head bolt + nut + washer for the u-groove bearing


Assembly is easy.
Strip the old cube head entirely, removing the metal frame that the stepper motor is bolted to.
Print all of the parts and assemble as such:

  1. Main Body to the cube print head
  2. Insert the support plate
  3. Insert the rigid plate
  4. Insert the E3D cooling tower
  5. Bolt the stepper in place, through the main body, support and rigid plate
  6. Assemble the bearing unto the finger and affix to the main body
  7. Insert the spring at the top - I used an 20mm bolt to keep the spring in place. It sits snugly on top of an M3 hex nut.

For cooling I printed one of these E3D v6 Hotend - 40mm Fan Duct as I had a 24V 40mm fan spare.
