Little cute marble spinner

thingiverse

A small spinner that I designed for not having to use the ball bearings as counterweight. There are several of these, but I wanted a spinner that lets you easily introduce the marbles and keeps them from escaping when you spin it. Unless you throw the spinner on the floor, the marbles will stay put. I also came up with this little cap so you can see the ball bearing while it spins. It's pretty cool to watch those bearings turn around in circles.
