Everything will be open source Boyan, that's why we are here..
i will share DXF and 3D models of course, we are thinking to have the complete panel re designed, let's see what i can do.....

So you guys bought a 3d printer.... well let me tell you, you will need a long time before you print rubber after plastic if is the first printer you have, is not an easy job, it looks like a joke, but when you start printing seriously( i mean accurate models) here is when your stress start :-)), happy head aches to you
Anyway, if you need help for the printer just ask, i'm happy to help, i'm in the 3d printer world for years, they have no secrets for me.
If you are courious have a look at http://www.thingiverse.com
