Fast Ball, with magnetic clasp

The Lightning_Bolt_Yellow.stl piece will need supports, the other pieces shouldn't need supports.

You will need to print off one of each file, except the "Side_Piece_Yellow.stl", you will need 4 of those.

Glue two side pieces onto both the top and the bottom pieces and glue the lightning bolt into the top.

After assembling the lid and the bottom you can glue the button and ring to the bottom with the hinge in place as you glue the ring down. Then snap the hinge into the lid.

You will also need 2 magnets (1/4" X 1/16"). Just glue them in place.

Netfabb seems to be gone so these files have not been put through a repair program. I've tested the preview from MakerWare Desktop and it seems like the pieces should print correctly but let me know if you have problems.

Tip: Print your bottom piece (dark blue 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.
