This was a high school pre-eng project I made for a class. I had a bunch of iteration files sitting in my computer for a while and I think I chose the right files, but print at your own discretion. To assemble: first, get a short strip of LED lights, a battery, ½ inch ON/OFF button, wires, and a large 3mm thick two way mirror. cut the mirror into 6 4" squares. The pieces may need sanding down at the top, again I created this a while ago and don't have a perfect process. Stick the LED strip into the circle tray, and lead wires out the hole to the bottom. Solder a circuit between the button, battery box, and LEDs. Place the tray in the cube on the stand, and add the mirrors to the bottom and slots. Make sure they are oriented to have the best mirror affect when the light is from the inside. Glue the mirrors in place, including the top lid mirror. Once assembled, press the button and you will have a new Infinity mirror cube!
