About this 3D model

I wanted a spinner that didn't have exposed outer weights. This design will either accommodate 3/4" X 3/16" button magnets or three pennies. I like using magnets because you can use them to make each other spin, stick to fridge, etc. To insert the weights just pause at the corresponding layer at the top of the magnets or pennies in each hole. I did not include spinner caps because there are already plenty of good designs. You can get the magnets at most craft stores, I picked up a 52 pack at Walmart for $6.
