I really like what RockStarAlchemist did with the case, but wanted one that would accommodate the mullet mod (which removes one battery section) and would also be less tall (because it didnt need AS much height).
notice http://www.thingiverse.com/thing:1637219 (This is wonderful btw)

Sooo, I created this one and made it so
1) the tinywhoop would only go in one direction
2) it doesn't have too much space to shake about inside
3) has enough room to hold my 6 batteries
4) wanted to play with curves.

TODO:
1) make the top cover.
2) fiddle with the overlap thickness (back wall seems too thin, but still works)

Edit 2016-10-13: Made top cover. Printing now. It will be super snug, so may need to make walls thinner, or scale up 1-2% or print in flex filament.
