WK9 M6 insert nut

thingiverse

I printed out the improved extruder for my coworker who had followed my lead and purchased the MPSM at his own expense. He brought the printer to work and we installed a glass print bed together. When I went to install the WK9, I discovered that he hadn't acquired the M6 nut as instructed. Initially, I thought our project was in trouble, but then I remembered that I still had access to my own printer. I fired up Fusion 360, imported an M6 nut from McMaster-Carr, and added a small reinforcement just in case the insert needed to be removed. After exporting the file to Cura, I printed it solid and it fit perfectly into place. While it may not be as robust as a standard metal M6 nut, it should serve our needs temporarily!
