The Hobbit does a really nice job with little effort on my part. I basically set the bolt into the carriage with the dremel on high speed and let gravity do the cut.
The only thing is, the notches have to have a slightly bigger gap in between the teeth and depth of cut. So I will try a 20 tooth gear instead of the existing 24 tooth gear and I will make the insert for the dremel slightly taller for a deeper cut.
Here's a pic of my first try:

I've been trying to find a hobbed bolt I can use with this build, without any luck it is time to get creative. I looked at a few different ideas on Thingiverse, but nothing was really designed to do the job right. Or it was for the wrong use.
Then I thought, how hard can it be to make one with my tools at home and this extremely useful 3D printer.
Here's what I came up with.....
This is called "The Hobbit", which is a fitting name for sure.
It runs off of bearings, just like all of my prints do, and it also locks into place for each cut.
