I originally made this to be made on my CNC Mill out of aluminum. Time, and lack of scraps lead me to just 3d print it. It works good for far with 3 Walls, 80% fill. I think using the right size collets you wouldn't need to jam the nut down so much as to break it.

Thanks for sharing! Do you think those corners will hold up to torque? Perhaps thicker is better because it's plastic.
