Nintendo Labo’s blueprint patterns are now available for free, online, through Nintendo itself — but remember that Labo requires more than just cardboard to work as designed.

Software, of course, is needed to govern the Joy-Con controllers’ behavior when playing around with creations like the fishing rod or the RC car. The patterns are mainly useful as replacement parts for those who mutilate the original cardboard cutouts or, down the line, wear out their creations.
