Mounts a pair of Bushnell binoculars in front of the camera on a Samsung Galaxy 6 so that the lens is peering through one side.
Included in the photos is the order of assembly, (after the adjuster knobs are in place).
The knobs use 3mm screws of various lengths, and 3mm set screws for two of the knobs.
There's one example of a photo (the wood ducks) taken using this mount, together with my tripod mount for Samsung Galaxy 6.
Getting the rear binocular lens lined up with the camera lens is the most important thing. That and the distance between the binoculars and the phone. The front adjuster knobs might be overkill.
Print the main part on it's side (with supports), so that perimeters wrap around the thin parts that grip the phone. That will avoid having them snap off at the lines between layers. This does make the print pretty tall though, at 85mm. Make sure there's clearance for printing something that tall in your printer. (Mine was pretty close.)
For the others, use your best judgement regarding orientation and supports. It should be pretty straightforward.
I had to sand down the channels and rails where parts sit next to each other. Just make them slide easily; there's no benefit to them being snug or having resistance. (You might even consider making them thinner before printing.) I also used the "Super Lube" in the photo. (Good stuff to have around for PLA projects anyway.)
