Electronic Pokeball (DIY)

Update 2016.10.10 -- added a modified bottom that includes a wobble-stop thingy and some holes to let more sound out.

Modified the pokeball with electronics to turn it into a success/fail or coin-flip type game.

Just for the fun/challenge of it! See vid here:

All the design files are included (AutoDesk 123D Design) if needed.

The top part is printed in transparent PLA to let light shine through.
