Howdy! This is my first model for anything printable so bear with me… This is a 2 and 4 key variant of a keyboard switch tester fidget keychain thingy… I printed the original and absolutely loved it. But I've always wanted to have something a little more rounded and I noticed I'd hold mine in the palm of my hand and roll my fingers over the keys. So I made it a bit more girthy to fit my habits. The switches should fit the same as the original. I may have adjusted the switches ever so slightly tighter as mine would pop out a little too easily. I also made the hole for the switches deeper to accommodate putting some foam in the bottom if you so choose to do the same! If you want to change the sound profile, try adding foam or changing the infill percentage! 

Printed with supports for the hook overhang and I recommend a .12 layer height to make the rounded nature as smooth as possible.
