Pokeball 2x2 extensions

The files included here are the extensions needed to make a 2x2 pokeball twisty puzzle. The base puzzle is a Mofang Jiaoshi MF2C 2x2. The caps on the corners need to be removed on the MF2C for the extensions to go into place. They should snap onto existing tabs on the puzzle.

There are 3 sets of pieces here:
pokeball1-4
pokeballfillet1-4
morefillet1-4 (the version shown in the full picture)

Each has progressively more fillets added to the pieces which should make the puzzle more comfort
