UPDATE: This design has a weakpoint which I have corrected in my next iteration. The new design, though very similar, is not compatible. See: http://www.thingiverse.com/thing:1014933 DESCRIPTION: I am working on constructing an interconnecting castle set. This can be printed without support material. There is a central piece with a gate, and various wall sections that interlock. I plant to add more pieces such as a larger tower, gate piece, etc.
