mechanical travel chess set

overview : this project is a portable chess set that includes a foldable magnetic chessboard, a full set of chess pieces and a dual compartment that is mechanically forced to open at both sides by using a dual rack and pinion system. i started playing chess at school again, but too many people play at the same time, so what better than to bring my own chess set! note : MAGNETS ARE COMPLETELY OPTIONAL! THERE ARE 96 MAGNETS TOTAL IN THIS BUILD - BUT THEY ARE COMPLETELY UN-NEEDED FOR TIME/COSTS SAKE.

why a chess set? : i got into chess in 2023 and have been playing inconsistently up until now - where i've started playing a little bit more consistently, since it's been a lot more common around my school to play chess during free lessons. there is only one chessboard in the entire sixth form lounge - so what better than to bring my own chess set that i designed myself! function & how to use : the chess pieces and board are oppositely , meaning they snap to each tile easily, allowing positions to be easily saved without easily knocking pieces off the board. the chessboard wraps around collar that holds 2 compartments that release with a rack and pinion mechanism - allowing all the chess pieces to be stored in the different compartments. overall dimensions : 58.00 x 194.00 x 58.00 note: this is NOT print in place, so each individual part will fit in a 256mm^3 build volume, but the entire build IS bigger than 256mm^3 :)

model build requirements : 32 x tiles (white filament) 32 x tiles (black filament) OPTIONAL: 96 x 6mm x 2mm circular magnets 16 x pawns (8 white, 8 black) 4 x rooks (2 white, 2 black) 4 x knights (2 white, 2 black) 4 x bishops (2 white, 2 black) 2 x kings (1 white, 1 black) 2 x queens (1 white, 1 black) 1 x left chessboard 1 x left chessboard right hinge 1 x middle left chessboard left hinge 1 x middle left chessboard 1 x middle left chessboard right hinge 1 x middle right chessboard left hinge 1 x middle right chessboard 1 x middle right chessboard right hinge 1 x right chessboard left hinge 1 x right chessboard 3 x pins 1 x compartment1 left 1 x compartment1 right 1 x compartment1 left 1 x compartment1 right 1 x collar top 1 x collar bottom 2 x spur gears 2 x m2 x 2mm bolts model build instructions : OPTIONAL: glue every magnet into every tile piece, making sure each magnet's polarity outwards is exactly the same. glue every magnet into every chess piece, making sure each magnet's polarity outwards is complementary to the chessboard's magnets.

glue the left chessboard right hinge to the right of the left chessboard. glue the middle left chessboard left hinge to the left of the middle left chessboard. glue the middle left chessboard right hinge to the right of the middle left chessboard. glue the middle right chessboard left hinge to the left of the middle right chessboard. glue the middle right chessboard right hinge to the right of the middle right chessboard. glue the right chessboard left hinge to the left of the right chessboard. position the hinges of the chessboards together. secure each part of the chessboard together using a pin through each hinge. glue each tile piece into place, alternating black and white in a checkerboard pattern. friction fit a spur gear onto the top and bottom collars, then bolting it down loosely with an m2 bolt. glue both halves of compartment1 together. glue both halves of compartment2 together. position both compartments over the bottom collar, ensuring the gears mesh. glue the collar halves together flushly, ensuring the top gear meshes successfully.
