Lissajous pattern projector

thingiverse

Human beings can control the fan speeds by adjusting an adjustable air valve that obstructs the airflow of two fans, instead of using electronics.\nThe airflow can be slowed down enough to produce fascinating pattern changes that make you curious to try them out.\nThree fans are powered by a 9-volt block cell. The three fans can be connected together seamlessly with no complications involved.\nTo facilitate easy sliding of the air valve over two fans, the mounting holes for these fans should be countersunk from outside, which requires some effort to do it manually with a drill of size 5mm.\nDon't let a machine damage your beautiful printed item; make sure to drill through carefully to avoid damaging your couple hours worth of hard work.\nThe third fan runs at constant speed consistently, and it works perfectly well.\nLaser machines need only three volts to run smoothly and operate without any hiccups or issues.\nInstructions for use:\nPrint the Lissajous pattern generator with its fan walls facing upwards towards the ceiling, making sure that there is enough clearance underneath.
