working 13x13 rubiks cube

this is a working 13*13 Rubik's cube I designed. as far as I am aware, it is the only one on this site (and the only files available on the entire internet for that matter).note: this is a difficult project to take on and it will not work as well as you hope unless you follow these precise steps. Filament: you can use either PLA or ABSPLA will be easier to print with and make the cube very strong.ABS will make the cube turn far better and feel very nice however it can be harder to print with, and you may struggle printing with it (though this depends on the quality of your printer). for the core however, you have to use either PETG or PLA as ABS may crack when you screw in the M3 boltsthe M3 bolts must be approximately 30mm long and depending on the accuracy of your printer and nozzle may need to be sanded on the end to achieve the optimum length. Printingin total you must print 4 of each piece in each colour other than the centre cap and centre pieces which must be printed once in
