About this 3D model

Since I wanted to stick a DUPLO brick to the feet of other objects, I modified the scad file with an extra 4th parameter (nibbles on or off) First try was: I imported models to Meshlab and killed the caps of the brick. A dumb way to it as the commenters pointed out :) This thing gave me the idea for a larger project: http://www.thingiverse.com/thing:2106
