About this 3D model

A larger knob for the Ulticontroller which can be operated with one finger. Modelled from scratch in OpenSCAD; this thing was inspired by [?ulticontroller speed dial knob](http://www.thingiverse.com/thing:27836). Differences: * larger dial * anti-slip-dents on the side * includes OpenSCAD-sources * connection hole has inlay to prevent slipping * smooth edges
