Laser sculpture

They craft intricate designs on the ceiling of a dimly lit space. The lasers employed are invisible to daylight. The pattern recurs after 4,867 rotations, equivalent to 9,734 minutes at half revolutions per minute or 162.2333 hours, which is approximately 6.7597 days. I've included an OpenSCAD file used for creating the components and a parts.txt file that lists the unused parts. For the power supply, I utilized an old phone charger and a barrel plug set on hand; however, any standard phone charger capable of delivering 360ma or more at 5v will suffice.
