Pokeball Grinder

Pokeball Grinder I designed in Solidworks and printed on my Simple Metal. It has been updated slightly after I had printed it. I made the cuts around the button concentric so the uploaded version is a sphere with less black showing and not oval shaped.

The grinder insert marked as "engraved" just had my user name around the rim, chose the non engraved one if you don't want to see my name, just added it for the fun of it. Let me know if you have any ideas to improve it and show me your prints!!!
