Collapsible Chessboard

thingiverse

This is a collapsible chess board designed to provide a full-size playing surface that can be folded up and taken on the go. If you like this, check out my remix that adds various designs to the pieces: https://www.thingiverse.com/thing:4193615 The default size of each square is 35 mm, and the assembled board comes in at approximately 280 mm (11-3/8") square. It can fold up into a stack in either direction about 2" tall or be folded in half, three rows, or any combination you desire. This design requires only four different pieces, with two distinct colors - or however many you want, really. For the purposes of this description, I'll use two (Colors "A" and "B"). The bill of materials is as follows: Square_MIDDLE (Color A): 18 Square_MIDDLE (Color B): 18 Square_EDGE (Color A): 12 Square_EDGE (Color B): 12 Square_CORNER (Color A): 2 Square_CORNER (Color B): 2 Hinge (Whatever color): 112 I've found that making batches of six works well for the squares, and for the hinges, I started printing in batches of a dozen or even up to 48. The key with the hinges was printing on a raft and positioning them vertically; it really helped improve the quality of the entire batch on my printer. If you have a solid printer, the squares will require little or no cleanup if it can handle the 1.5 cm bridge. Find what works for your printer, and as always working around a bit helps smooth off any burrs and smooth things up. My printer is relatively low-end, so I experimented with the clearance on the hinges to find what worked. If you print this out on a really nice printer and discover that the clearance is too loose, let me know and I can create a part with tighter clearance for you. https://www.youtube.com/watch?v=cD9noHQuFN4
