I've done enough practical design today, time for some fun. These pointy knobs are meant to be uncomfortably prickly on your grubby little hands. You can use them to keep the cookies at bay, or to take your mind off some other pains. The stellated dodecahedron shapes have two choices for bases and the other is a non-geometric pattern of spikes.
While I wanted to make these horribly sharp, long-pointy things, I also wanted them to be easily printable. No supports needed. As long as you have slower speeds or plenty of cooling, the overhangs will remain tidy. Hole is 2.6mm for 3mm fastener to self-tap. Printed in a variety of PLA filaments with 15% cubic infill, though gyroid or non-directional fill would also work nicely.
