Mount bracket for attaching a Dremel 4200 to a MYDIYCNC BigFoot machine. I found the original spindle less than adequate. Special thanks to MGX for creating the screw head. I modified his design. When mounting the Dremel, you have to push the top bracket's legs into place to line up with the mount holes. It is VERY tight. This was intentional to hold the Dremel and prevent any issues. I printed mine on a DaVinci at solid (90%) with thick skins and 0.3mm layers. Happy Making.
