Just in time for Halloween, this simple projector is designed to project images with the help of a flashlight. Simply place a small flashlight inside the box and slide a lens onto the front to project the image of your choice! The included STL files have 4 Halloween themed lenses but you can also create your own.

Print instructions

The pictures show the files printed with Prusament Silver PLA at 0.3 mm on a Prusa i3 MK3s. The total print time with the projector box and the included lenses is 6.25 hours. The front portion of the projector box that holds the lenses requires support material due to the overhang.

The flashlight used to project the images was an EverBrite 9-LED with a luminous flux of 20 lumen. The resolution of images will likely vary depending on the amount of lumens used. The provided STL files will fit a light source about 10cm long and a diameter of 4 cm.
