spiky clicky stim toy

Inspired by a video showing a spiked cylinder ("Ouchie") that is intended to stimulate a bit of pain, which can actually help focusing better in certain conditions (like ADHD), I wanted to quickly design such a thing (but with hex spikes) and test what it's about. I showed it around and instantly two people wanted to have one, and I also got the suggestion to add a clicky to it - so I did. This is my first clicky fidget, but it turned out quite nicely. I also made a version without clicky but with a cavity to be used as container. Printing: Standard settings, though I prefer to tune down acceleration for the outer perimeter quite a bit. Good bed adhesion is required. Assembly: See picture. If it doesn't turn well, try grabbing the knob with some pliers and turn the handle for some rounds to break it in.
