Coolpix Front Element to Canon EF Body Lens

Take a Coolpix L830 and remove the front lens element with a screwdriver (this is easily reversed). Keep the lens in it's plastic mounting Print the files in a dark colour, I did PLA white and had to tape the whole thing up to prevent light leaks. put the lens upside down inside inner-holds-lens.stl, this lens is then fixed in place by lens-hold-ring.stl. If the lens is not upside down, it won't fit. Attach the outer tube (outer-on-EF-mount.stl) to the camera body Put the tube now containing the lens inside the tube connected to the camera so the open end is facing the subject, opposite to most lenses. 6, focus with your finger by pulling and pushing the inner tube. Photos are examples taken with this print on a Canon 400D.
