Sudoku (travel edition)

thingiverse

This year's christmas present for my dad. Thought I'd share it with you :) Instead of solving new ones in books and then throwing them away it seems a bit more sustainable when he can reuse them at least a couple of times. The case measures roughly 180x180mm (without the hinges and therefore should hopefully also be printable on the Prusa MINI). The number chips are 12x12mm and when printed with layerheight 0.2mm you can switch filament after 2 layers and then again back after another two until the top where you could do another switch every 2 0.2 layers to get nicely highlighted numbers. The hinges can be attached with 2 x M3x5mm socket Cap Screws and M3 nuts (i recommend additional glue), and need 6 x M3x40mm socket Cap Screws for the latch mechanism and to connect the two case halfes. The sudoku puzzles are from https://www.printablesudoku99.com/ when printed with two pages per DinA4 sheet and cut out to 70x70mm squares, they fit exactly into the case.
