Single Extruder - Dual Color - Chess Board

This single file design for a two-piece chess board was inspired by the Single extruder, Dual color contest. I wanted to create a new way to mesh symmetrical objects, and discovered a very similar process to achieve similar results. I am relatively new to 3d printing, and am unaware of a term for the process I used. If you combine your geometry with one that is negative and rotated 180* on the Y-axis, you will get a part that. when printed twice, will fit together nearly seamlessly. It is possible to create many shapes this way, as it is simply the original “Single extruder, Dual color" design with a twist. you have to keep in mind it is very important to remember including tolerances for the parts to fit. I hope this helps broaden the creative range of all modelers. If there is anything that I can answer, or any tips you have, please let me know!
