Anyways, today I made my first nubs. I'll take apart my hopup tonight and see if it fits. I know that most people wanted the extended concave nub, but I decided that the natural progression was to go from the extruded (where each 2d cross-section is identical) and become more complex. A few problems I encountered were that since the nubs are so small, on the final pass, the nub gets "kicked" off the tape, and leaves a little ledge, but changing the feed rate made this better, and I believe getting a stronger tape and using a smaller bit (a 1/32 rather than a 3/64) should solve this issue.

Sorry for the crappy pics... all I have right now is my phone, and the lighting isn't the best. The one on the top angles downward, and the one on the bottom slopes downward and becomes flat.

I am thinking of starting alpha trials. If I were to do something like one angled nub and one flat nub for 5$ shipped, would anybody be interested? Otherwise, I'll do testing "internally" (with a few of my friends) and sell them for 5 a piece + shipping. I decided it would be better to get these two nubs out first then work on the concave nub later, as I can use things I learn now for the concave nub, but that wouldn't work the other way around. Tell me what you guys think

flat nub

angled nub

My roommate had a camera. The one on the left is the angled nub and on the right is the flat nub. On the angled nub, I plan to use a smaller bit and then make the left part a bit thicker. I'm working on getting rid of that downward sloped part on the angled nub, and I believe it will be solved when I use a smaller bit and changing the design a little bit.
