This is based off of the "Pokeball, with magnetic clasp". However I have remade all the files (except the hinge) so this ball may not work well with the parts from the original or any of my other remixes.
With this version the lid is in one piece and you will have to paint it. If you prefer to print out each color as a separate part please see http://www.thingiverse.com/thing:955822
Print the Lid, Bottom, Button and Ring. After printing the parts you will want to paint everything. From there glue the button and the ring to the bottom with the hinge in place as you glue the ring down. Then snap the hinge into the lid.
I've had issues printing the Ring file with only one shell. So you might want to print the Ring with 2 shells. All other files I printed with 1 shell.
Lid_V2 and Bottom_V2 have thicker rims/ridges.
You will need 2 magnets (1/4" X 1/16") and just glue them in place.
Tip: Print your bottom piece at a higher in fill percentage, around 40-50% and then all the other parts at 5-10%. That way it will be bottom heavy and not roll around as much.
