A Spiderman lightbox. Designed in Fusion 360. The main body is printed face down at a 0.2mm layer height and the back panel printed face up at 0.28mm height. I designed the back panel with 2 holes to enable wall hanging and 4 holes to screw to the main body (I have using glue!). I also added a small hole in the main body to add the USB wire that connects to the internal LEDS. I added the links to what I used below. The screws I use are 1/2" #5 wood screws, but you can use any other type of small screws.
