thingiverse

Using multiple hinges, the "do not" slips quietly behind the wall, revealing only a hint of disruption. Assembly Instructions: Print out all components. Position the "do not" unit into its designated base. Securely attach the lid to the top of the base. Tie strings (preferably with an intricate figure-eight knot) around the "disturb's" circular frames. Affix the strings firmly to the underside of the base.
