Giá đỡ universal Sherpa Mini & Micro cho Ender 3

Did you know that Annex Engineering made a wonderful and lightweight extruder you can print at home?

The Sherpa Mini and Sherpa Micro is the lightest extruder. You can mount it with the Ender3 and you'll get a direct drive extruder and you can print TPU with it.

Two things have to get: one BMG clone extruder to harvest the inside of it and you have to buy either an LDO motor or Moons' motor Nema14 and mount it together.

Assembly instructions

I recommend to print this holder (and the extruder) from ABS or at least PETG for better heat resistance, but my Moons motor bearly gets warm after a couple of hours of print.

The Mini and Micro extruders are mounted almost the same positions but they not. The Annex Engingeering made it with the right screws is a bit overlapped each other, so the copper heat insert should insert from the other side to touch eachother. The plate is 7mm thick, so you can insert one 4mm and one 3mm copper insert.
