Dremel groove cutter

thingiverse

I wanted to "route" a 6mm groove into fiberboard to allow for a cable to pass between the board and the wall. Didn't have a router but I did have a Dremel. This print threads onto the Dremel's plastic thread and holds it at a 63º angle. You can adjust the depth of the "cut" by mounting the sanding bit further in our out of the chuck.
