The 123D Fab! Cardboard Construction Kit is a collection of 100+ laser-cut pieces of cardboard and pieces of dowel that allow you build all sorts of crazy creatures. Connect the dowels to gears and you can add some movement to it as well!

The 123D Fab! Construction Kit was developed by Oliver Kreitman during his stay as an Artist-In-Residence at Instructables. Other creations of his include a tar and feather gun and a robotic claw business card. You can also read about the development of the 123D Fab! Construction Kit here.
