This is a cap that protects the lense of a Polaroid 320 camera. It was designed to accompany my other part for the camera, which was a fine-tuner knob for the lense tube. That part simply presses onto the tube, and has a little notch for precision. After that is on, the cap securely fits onto that, therefore covering the lens.

    The parts were created in such a way that no glue is required, and should be a tight fit. I apologize that I wasn't able to print it out because I don't have a printer. If I were to win, I was going to buy a printer.
