Phone -> Otoscope Adapter (S4 -> "Dr Mom")

thingiverse

Connects a "Dr Mom" otoscope to the camera of a Samsung Galaxy S4 phone, allowing you to capture videos or stills on the digital camera. Inspect your own ears! (Carefully!) Amaze your friends! Look at small things! Instructions Just slice and print. It isn't perfect, the otoscope snaps in reasonably well but it still has some freedom to wiggle. I find it works best to use it the same way you'd use an otoscope if there wasn't a phone attached to it -- holding the handle in your hand (i.e. don't hold it by the phone, hold it by the otoscope, with the phone upside-down). Use the camera's "digital zoom" (cropping) to make better use of the phone as a viewfinder.
