A chess board designed for (reasonably) easy printing and assembly using a hole-and-filament-peg method. Assembled board is 34 cm x 34 cm (13 x 13 inches). Designed especially to go with my OpenSCAD Chess set http://www.thingiverse.com/thing:585218

Update, August 22, 2015: Entered the chess set at the Montgomery County, Maryland Agricultural Fair under the category "Crafts: handmade toys and games", and won first place! Perhaps one day they will have a category "Crafts: 3D printed". . .

Update, November 29, 2019: Doug Probst (https://www.thingiverse.com/airscapes) has provided a very nice set of tools for helping with the chess board assembly, here: https://www.thingiverse.com/thing:4009379. Use the grip to hold the part board_tile while sanding. Use the filament cutter assembly with a razor blade to cut the filament pegs to exactly the right length. Thanks, Doug!
