UPDATE 10/04/2016 - I made V3_Main_Frame. It has a flatten top to make printing easier as requested. It should be compatiable with all V2 parts. BUT I have not tested it, so print at your own risk and please let us know how it turns out in the comment section! If you dont want to take the risk, then I also left the original V2_Main_Frame file up. -Thanks
UPDATE 08/26/2015 - I made this file "public" on Onshape. So if you want to edit it or add new stuff to it you can. Just go to https://cad.onshape.com/signin and make a free account. Then search "Pokeball by SpragClutch" in the public area.
UPDATED TO VERSION 2 ON 06/13/2015
This is a workable Pokeball that opens and closes. It is 3" in diameter. (7.62 cm) Made it for my nephew. Enjoy!
This is version 2 ("V2" in file name). I have printed and made version 2. It is good to go.
