Cap for coffee grinder

A cap for my manual crank burr coffee grinder, since bits fly out of it when you get towards the end.

Here's a link to the grinder model: [Kyocera Ceramic Coffee Grinder](http://www.amazon.com/Kyocera-CM-50-CF-Ceramic-Grinder/dp/B003S9XF7K).

Updated May 27, 2014: Final version! I've added some instructions for properly scaling the design in MakerWare to get the right fit. I also make the edges smoother in OpenSCAD.
