Basicly i really wanted Doug Marcaidas karamball as a fidget spinner/keychain type of thing, i do fidgety things a lot when thinking or extremely bored. The problem was the shipping, import tax and the actual price of the product, so i designed my own (with a lot of help from a friend and https://www.thingiverse.com/waessman) and spent weeks trying to perfect the print as much as possible.

Unlike the original this one could technicly be used for self defense by a trained individual if you up the infill to say 80%, therefore use it with caution and i will not be held responsible for how it is applied or used by other people.

I still recommend you buying Doug Marcaida's Karamball at the link below, this was just a test for myself and a solution to a problem.
