Prusa Direct Drive E3D extruder mount
thingiverse
This is my take on a direct replacement for the direct drive extruder to allow an E3D hot end on a Prusa style printer. It requires 2x M3*4 for clamping the E3D hotend in place, and 2x M3*16 screws to complete on the back for the belt to loop around. Currently, this is a work in progress so some updates may happen. This design uses relief holes to help prevent cracking from the plastic warping. I recommend printing in ABS if possible. If you have any questions, feel free to ask. I've included STEP, STL and IPT versions of the model.
