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. But I also designed a version that uses the space inside as a small container. The lid can be turned around to be operated by a small coin (see image).

There's also a non-spiky version with a bigger knob available.

The 3mf contains both versions and uses mainly standard settings with a few unimportant changes (outer wall acceleration reduced, crosshatch infill).

Assembly: See picture. If it doesn't turn well, try grabbing the knob with some pliers and turn the body for some rounds to break it in.
