Description

The mechanical laser show is a device that projects a pattern by quickly moving a laser. It's hand powered, 3d printed, open source, and free to print.

For more information and shots of it in motion, see this video:

Printer:
Monoprice Mini Select

Notes:

Each part has different print settings:
Cams (2)
15% fill, supports, no build plate adhesion
I recommend increasing the "Support Distance X/Y" to 1mm or more

Crank gear
15% fill, supports, large brim

Back Plate
15% fill, supports, no build plate adhesion

Front Plate
15% fill, no supports, no build plate adhesion

Crank handle
100% fill, supports, large brim

Note- this piece has an arrow telling you which way to crank (clockwise). If you want it to look great, sand down with 100 grit sandpaper.

Fasteners (X axle + Y axle + 2*Bolt)
50% fill, no supports, large brim
Note- the X and Y axles are different parts. One is right hand threaded and the other is left hand.

Parts to buy:

Rubberbands

It is important to use light rubber bands. Normal bands can provide too much force.

Optional Parts:
Ring to hold down the power button on the laser:
