This needed to be done! ** I've designed the board game in such a way that it neatly fits inside the slide lid box. Tolerances have been taken into account already so no extra adjustments needed. The board is cut in 9 5x5 space squares, named in matrix form (a_{ij}) from 11 to 33, the "assembly" of which needs to match the board image here - tell me if you'd want them to have this matrix id on the actual piece. The markings on the board are debossed, so you can "fill" them in with something like nail polish (the 3W, 2W, 3L and 2L as well as the center star) When placing the pieces in the box, sandwich them between board pieces 25 at a time ( like in one of the images here) and then simply place the remaining boards on top of the others. The box will have a PERFECT FIT. Since the letters are embossed, if your printer allows it, you can change the filament so that they stand out better (pause, change filament, resume printing). I've also included a lid without the words "English version" if you want to print the pieces for a different language (the letters have the same values but a different distribution - google or search on wikipedia for the exact count), reason why all the letters are also uploaded individually. Couldn't work my way around the rack (something more compact/foldable would be nice. ** like it, download it, share it
