Laurens Valk published building instructions (made with Google SketchUp) for his Brick Sorter. I added this project to the NXTasy repository ‘Projects’ page here. That page contains over 20 NXT models with links to building instructions, made by various authors.

With the released of LDD 2.2, making building instructions is even easier then before! I invite everyone to share LDD files and building instructions in our repository, simply by emailing me with guy (at) nxtasy.org.
