Ball Bearing Spinner Fidget Toy - REMIX for M10 Nut

Firstly, credit to the designer Keshyden, with original design here: http://www.thingiverse.com/thing:1794875

I personally don't like the usage of 4 bearings, these things are not cheap in South Africa. So i modified it to take 3x M10 nuts rather. Everything else remains the same, and can be downloaded from the original creators thingy page.

Hope i can save someone some money somewhere :)
