Abstract in different language:	This technical and didactic project aims to connect work with a computer and a smartphone with manual activity. Working with a computer involves creating and editing .stl files for the 3D printing. Equally important is the manual part of this project, which includes not only the compilation of the puzzle as such, but also the editing, and especially the application of code. The last step is to use a smartphone and scan the code, which then launches the language game. Alternatively, you can choose any other activity you like. For this particular project, 64 pieces in size of 25 x 37 mm, printed from black PLA (polylactic acid) filament, were chosen. They are identical in shape, which is an advantage in printing, but a consequent disadvantage when putting the pieces together. Because of that, 32 pieces are hatched from right to left and then the other half is hatched in the opposite direction. An optimized printer setting was used with 30 % infill density. Absolute accuracy and the best appearance were not the main goal. Furthermore, the size of the pieces can be changed.The code on the puzzle was then transferred from the negative of the code printed on self-adhesive paper. From the negative, the areas that we wanted to transfer to the puzzle were cut out and this shape (code) was spray-painted. The size of the side of the assembled puzzle is 200 mm (25 mm edge of the piece x 8 pieces), so an ordinary printer and A4 paper willsuffice. The content of the code depends on the specific adjustment of the activity. The aim of this project was to connect IT with foreign language teaching. Therefore, after scanning the code from the solved puzzle, an online language game opens, where students can practice specific vocabulary. The URL was shortened because the data contained in the code were limited to 8 characters.
