This is a key duplication machine that was designed for a different rotary tool that I remixed to fit dremel series 100 and any other rotary tool with 3/4 x 12 threads. It has also had a thicker base added to it as well and been mirrored to change the direction the debris is thrown, so that it will go away from the operator. I am not the original designer and he deserves credit for the majority of this design. I printed it in this blue abs for strength. On a Kobra S1. I used an upgraded hardened nozzle hotend and the print took less than a couple of hours at 100% infill. Links to the items I used are below
