About this 3D model

There is one very common operation that has to be done in nearly all the designs: beveling edges. It can be done on the convex side, for avoiding sharp edges, or on the concave side, for reinforce the part (avoiding the 90 degrees connection between parts). With the bevel library I am developing doing these two operations is a piece of cake. I have given some examples in this post: http://www.iearobotics.com/blog/2012/09/13/enhancing-openscad-ii-bevel-library/ The bevel library is part of the obiscad tools I am developing: https://github.com/Obijuan/obiscad More information in this wiki (in Spanish): http://www.iearobotics.com/wiki/index.php?title=Obiscad Many thanks to Miguel Angel de Frutos (MAF, http://www.thingiverse.com/MAF ) for his technical advices
