Support for J-head on Printrbot Simple Metal

thingiverse

I recently upgraded to the latest Alu Extruder V2 and discovered that my E3D and J-head hotends did not sit securely enough. To solve this issue, I designed and built a shim to support the mount. The shim attaches to the neck of the hotend where it is secured by another printer's frame, allowing the hotend to be inserted into the extruder and then attached using three 3mm screws. Once loosely fastened, these screws provide enough stability for the second screw meant to hold the hotend in place to be tightened tightly. The design had one initial problem - the holes didn't line up perfectly on my printer. However, I corrected this by moving them myself. In addition, a new mounting tab was added as part of the update. It's worth noting that I didn't revisit the original screw hole locations on the shim due to not using it anymore. Instead, I decided to move forward with the design modifications made on my updated version.
