Digiscope Mono/Binocular Phone Bracket - Parameterized

thingiverse

An eyepiece alignment bracket that holds your phone against your binoculars (or telescope) eyepiece aligned properly, as well as an optional second piece to use the other eyecup to support the rest of the phone. Makes it so you can hold and focus the binoculars without an extra hand for the phone, assuming you have a nice tight fit to the eyecups. Not responsible for dropped phones :-)
