Handheld Light Graffiti Projector

thingiverse

This is a very customizable kit that will allow you to use a very bright LED flashlight to project an image onto a surface with a camera lens. See http://www.disruptivelyuseful.org/ for a great overview of how this type of projector works and how you can build one yourself out of parts from the hardware store. Non-printed parts: Flashlight Lens 4 Hose Clamps Assembly: Use the Fusion 360 file to change the inner diameter of the caps to fit your flashlight and lens. Go to Functions and change the diameters to your flashlight and lens diameters and everything should update automatically. Print both caps, the main body, and as many slides as you'd like. Attach the flashlight and lens to their caps using hose clamps. Use the remaining hose clamps to secure the caps to the main body. Print (or draw) out the design to be projected and use clear tape to attach upside down to the slide. I'd like to encourage people to remix the caps to fit the lenses/flashlights that work for you.
