Printed upside down, I used black PETG, 0,2 mm, 0,4 NOZZLE
The author remixed this model.
I was fully satisfied with this holder on my MK2s and wanted the same simple one for my MK4. I didn't find the same type so i remixed the original one. (Only adjusted the size to fit MK4 frame).
Mounts to back side of the Z frame with 2 M3x10 screws.
