Well, you might have around in your kitchen some grinders for pepper, salt, whatever. They are usually pretty high devices that tend to fall from their normal standing position. The solution would simply be to provide a kind of support that will (oh, physics!) enlarge the area of the base, or kind of a "roots" to make it more stable on the table top.
We got inspired from http://www.thingiverse.com/thing:26227 *), on the root part and created a... grinder pot.
After trying with PLA/PHA from ColorFabb, we decided to give SemiFlex a try and it was a good thought.
L.E. Printed one in Taulman's t-glase Red. Used same settings as for SemiFlex :)
*) We do think this is not a derivative of the inspirational model, but just a brand new model with a totally different destination and definitely made for 3D printing!
