Additional parts needed:
  • One spring. Ballpen spring works fine for me
  • Three screws. I used three 3x5 mm screws from my junk
  • One hobby knife blade #11. (https://a.co/d/eyljeUE)
  • A short (~17-18mm) Bowden tube. 
Printing:
  • I printed as oriented in the STL files. I tried different orientations for the blade holder, and this is the best for strength.
  • PETG preferred
  • DO NOT add support to the blade slot of the blade holder. Otherwise, you will not be able to insert the blade. X Max 3 can do a good job printing the overhangs for the blade slot.
  • Use tree support for the Bowden tube collet.
  • Print the included clamping clip or use any of your existing ones.

Assembling:
  1. Carefully insert the #11 hobby knife blade into the blade holder. Don't cut yourself. Note the orientation. I used another hobby knife to push the blade into the slot.
  2. Put the blade holder on one of the sides of the casing. Note the joint and orientation.
  3. Insert the spring. There is a knob on the blade holder and a groove on the casing.
  4. Close the case carefully without the spring popping out. Yes, it is a bit tricky.
  5. Secure the case with the screws.
  6. Try the cutter. It should be able to move and rebound smoothly.
  7. Insert the Bowden tube collet on the top. Fix the collet position with the clamping clip.
  8. Insert a short Bowden tube at the bottom.
Installation:
  1. Carefully remove the cable chain and Bowden tube.
  2. Align and insert the short Bowden tube into the extruder and mount the cutter to the cable chain hole platform.
  3. Make sure the cutter is level.
  4. Replace the cable chain.
  5. Insert the Bowden tube into the cutter. Make sure it is fully inserted.
  6. Place the trigger to the far left of the printer frame. Make sure it touches the end.
