This is a 3D chessboard inspired by Star Trek, including a matching set of low profile chess pieces. It can be disassembled and transported easily. See instructions for required materials and assembly notes.
For "standard" rules of play, and the most easy-to-follow explanation of the game I have found, I refer you to Charles Roth's site at http://www.thedance.net/~roth/TECHBLOG/chess.html.
Additionally, there is a slightly different set of "tournament" rules maintained by Jens Meder at http://home.arcor.de/jens.meder/3dschach/chess3d.htm.
Thanks for pointing out the "tournament" rules goes to Doug Keenan, http://www.thingiverse.com/dougkeenan. Doug also has created an excellent 3D (and 2D) chess program called Parmen, available along with many other related resources at http://www.parmen.com/.
Note that this design does not allow attack board inversions... so you can just play without inversions.
Requires a length of 1/4" threaded rod, some fender washers for a base weight, a cap nut that fits into the top board, and a wing nut to hold it all together.
Some parts have additional material that needs to be removed/cleaned up before assembly. This includes small rafts at the corners of the base and boards, and on the attack board pins, which help them to stay on your build plate without warping or popping off. The holes where the threaded rod goes through the base and main boards must also be drilled or cut out.
The attack board pins (ab stem pin.stl) are glued into the attack board stems (ab stem.stl) to form the finished stems. You may need to clean up the holes in the attack boards and main boards, and sand the stem pins a little, to get everything to fit together properly.
The black squares are printed separately and then glued into the various boards as an inlay. There are separate files for the corner black squares as well as the black squares on the attack boards.
You will want to glue some felt on the bottom of the chess pieces, to keep them from sliding off the boards. I also glued felt to the bottom of the base.
