Designed for the Nikon Aculon A211 binoculars. It consists of two parts. Different phone mount clamps can be attached to the base part. So far I made two clamps, one that works for Samsung Duos / Ace, another one for the Iphone4s.Edit: Added Iphone 5 clamp. Note it is not tested.Printing:I used ABS and printed with 50% infill on my Ultimaker Original+. No supports are needed. Layer thickness was 0.15mm.I have not tested the design with PLA, so I don't know how well the snap-together connections work with PLA.
