Laser sculpture

thingiverse

Draws ever changing patterns on the ceiling of a dark room. The lasers I used are not visible in daylight. Pattern repeats in 31 * 157 = 4,867 rotations or 9,734 minutes at 1/2rpm or 162.2333 hours or 6.7597 days. I included the OpenSCAD file used to create the parts and a parts.txt file that lists the parts that were not printed. For the power supply I used an old phone charger and a barrel plug set I had laying around so I specified that in the parts.txt but any old phone charger that puts out 360ma or more at 5v will work.
