Foot Massager - Agressive

Keep your feet busy and stimulated even while working long hours at a desk. This is a simple, one-piece, no-support-needed foot massager. This one has more aggressively shaped points with spherical nubs on top, making it even more aggressive than most. Finely grooved rolling edges to work on carpet or hard flooring. There were many foot massagers online already, but the ones with aggressive teeth required supports. Many were just too complicated, with many printed parts to assemble, and some needing additional hardware. The simple ones didn't have very aggressive teeth or had teeth that would need supports. I knew what I wanted, so I just made it in Fusion 360. It prints on its end without supports. No assembly is required. Print it. Use it. 
It's about 4 inches (100mm) in diameter, and the toothed part is about 4 inches (100mm) wide.

This one has pointy-er spikes with little nubs on the tips for a more aggressive massage. My original one just wasn't doing it for me, but may still be good for people with more sensitive feet.
