i got the idea of the fidget spinner because i have my own and a lot of people wanted to use mine while i was using it. so i figured why on just make one and when people ask to use mine they could use the 3D printed one. once i got into tinker cad i just wanted to make one and after got my 3 cylinders and got the correct whole sizes I had to pick a color. after that i noticed i was thinking to hard and just chose black. so then i just started printing and it was a success!
