Summary Saw a video of a similar one so I figured I'd design my own that better fits my hand. All it really does is spin and to be honest I don't know if its worth the print but I've uploaded my version all the same. You will need at least a bearing for it to work, I've used 4 x ABEC 7 and it spinns really fast with the extra weight at the arms. (You might need to sand/file the center B part a little to fit inside center A. I've mede it a snug fit so it would stick together well)
