Holy cow, these fidget spinners are awesome! 3D printed with high quality skateboard bearings and chromed ball bearings, these aren't your convenience store spinners! Every one I make is hand tested to spin for over a minute.
**WARNING** - This design is sharp and adult supervision is strongly suggested. The saw portion is ultimately made of plastic but can cause injury and scratches if spun against the body, ears, mouth, eyes, etc. This is a spinner made for adults if there ever was one!
