Pokeball (added durability)

After my 8 year old broke the original ball by dropping it on the wood floor I revised the original design to be more durable and have more surface area for adhesive.

I took the original .stl files and revised them in TinkerCAD to add deep teeth to the top ring that passes through the bottom ring and set further in to the bottom half of the ball. I also increased the size of the hinge by around 300%.
