35mm Clicker

This is a modified "top frame" for Schlem's 120 Film Pinhole Photography System found here: https://www.thingiverse.com/thing:495230. I used a #6-32 x 1/2" flat head screw to attach the clicker box to the top frame. The box resonates as the point clicks through the sprocket holes on 35mm film. Theoretically, 14 clicks will get you to the next frame, but I use 15 clicks in practice. You will have to tap the clicker box with a #6-32 tap. You may have to use a countersink bit to remove a slight bit of material where the screw head sits in the top frame. The point may stick to the box, so cut it loose with an exacto knife.
