About this 3D model

The goal is to build a frame model for a 3d printer using aluminium profiles and accessories using the library profil3030.scad from http://www.thingiverse.com/thing:15026 Currently there are four demo frames: * a 3D printer like with bed. * a CNC with rods. * a CNC with pinion and racks. * a triangular frame. All the frames are parametrics. Update: 2012-02-05 changed the triangular frame (frame4) to be parametric like the rest.
