About this 3D model

This is a Helper to sprinkle chocolate-powder on a cappuccino in a spiral-design.But it is also usable as beer coaster...I have no 3D-Printer, so this device is not tested yet.Warning: The scad compile keeps more than 30 minutes. Update I added a mashup with the Debian-Logo (http://www.thingiverse.com/thing:4687)
