Comfy Clicker Fidget - Minimalist

This specific model will likely only work with PETG, possibly PLA.

I printed a few different box-style fidget toys, but could not shake the feeling that they were uncomfortable to hold.

This was one of the iterations I made (and I made MANY) that has a more curvy frame.

It can be finicky to assemble as there are no real tolerance allowed on the shafts holding it together. At the same time, any rough print edges would cause it to not fit, so you might have to file it down. The PETG is flexible enough to squeeze in and hold, PLA might work, TPU requires thicker walls.
