A Peekaboo Cat lightbox designed in Fusion 360. There is the main body which is printed face down at a .2 layer height, then the back panel which is printed face up at the same layer height. The back panel has two cutouts for the USB-C connected to power the internal LEDS as well as a switch to turn the lights on and off. Links for the USB-0C connector, Switch, and LEDS I used are below.
