The Italian artist Bruno Munari began building "useless machines" (macchine inutili) in the 1930s. He was a "third generation" Futurist and did not share the first generation's boundless enthusiasm for technology, but sought to counter the threats of a world under machine rule by building machines that were artistic and unproductive.[1]

Was originally a test print; however was perfect for the final product
The hinge was tested many times to find the perfect size of the pin hole to have a piece of 3D printing filament to fit
The switch hole was tested to properly hold the switch with a practice Heat set insert.

The Construction of the useless box had some unforeseen problems, starting with the motor not being properly meagered making placing it inside difficult. The other problem came from the wires getting in the way of the motor because they weren't measured in the digital display; some wires were bigger than needed, others were too short. Another issue was that the arm intended to hit the switch was loose on the motor, requiring tape to secure it in place. Lastly The filament used to work as a needle in the hinge was too tight as seen in the video, requiring it to be pushed down to close properly.
