Hemera Prusa i3 MK3 & MK3S Mount

!!!IMPORTANT !!! I will not be making any further progress on this design. It has officially been abandoned. However, if you are still looking to upgrade your Prusa printer to a Hemera extruder, please check out the fantastic design at https://github.com/tetra3dprint/HemeraOdyssey. OK. Very important notice. I have just noticed a massive mistake that I made. The holder fits MK3S, but it is impossible to assemble. I will modify it in the next version. In the meantime, it still works well with MK3 as of 14.01.2020. This design is still a work in progress. I have cleaned it up and made it suitable for both MK3 and MK3S. The screw spacing should fit. However, please keep in mind that this is still a work in progress. I have a few more ideas on how to improve upon it. So far, I have allowed for two cable ties for cable routing (not yet tested). Mounting holes are 4mm to allow for brass inserts. I have changed some tolerances from the base design to provide a tighter fit. Additionally, holes for mounting the extruder allow for a washer and spring washer. I will post some pictures once it is fully mounted. The next step is to move the bumper higher so that it collides with the part without needing the bumper part. The motor is held in place by an M3 5mm long screw with a 0.5mm thick standard M3 washer and a 1mm thick spring washer. The PINDA probe screw is an M3 10mm long screw with a square M3 nut. I hope you like it.
