About this 3D model

Based on Reprap Pen Holder: http://www.thingiverse.com/thing:31983 i updated the OpenSCAD (attached) to fit the penholder on my battery holder: http://www.thingiverse.com/thing:109807 In this way the Micro-Hexapod: http://www.thingiverse.com/thing:5156 (by ljon) http://www.thingiverse.com/thing:34796 (remixed by carlosgs) becomes a drawbot :)
