ANSI threaded barbed insert, v2

This is a fastener that could be used in certain materials. It works like a nail, except there is an ANSI thread on top. When you force the barb into the material, the counter-barbs should dig in and prevent the fastener from being removed easily. Then you can attach a threaded fastener to the top. The main shaft should probably be a little thicker, but this was a conceptual approach. I may or may not be able to do a force analysis on it. This can be printed, but then the tip would probably need to be machined. **I would probably scale this by 3x in order to print it.** ****** VERSION 2 ****** I made the design a little more proportional, realistic in terms of size. I also looked up print filament resolution and this one should be a little more feasible on a 1:1 scale. If you download this, and try to print it, upload a picture! I would love to see if it works. ****** V3 ****** I attempted to add a cutting tip, like seen on traditional nails. Not sure if it'll print out though.
