The button click fidget is a modification of the Snappy Fidget Button. Here’s a link to the creators page. He is an inventor and has created many amazing 3D printable designs. This modification extends the main body, tapers the shape and adds a wavy texture. At it’s core, it’s a button that you press that has a satisfying click. The wavy texture on the body adds grip and feels good in hand. It is made from 3D printed PLA plastic. I’ve decided to print it completely sold to add a little bit of weight. It takes a lot longer to print parts solid, but I think the weight makes for a better hand feel. There is a rubber o-ring at either end to prevent pinching. The slider is made from two different kinds of PLA, the blue parts are a matte PLA which has good grip and the black is a smooth PLA.
