Digiscoping.

Frustrated with the expense and jankiness of digiscoping adapters, I created a free, customizable, 3D printable, model to adapt any phone to any spotting scope or binoculars. All the dimensions are parameterized - no 3D model experience necessary.

The phone is secured and aligned to your binoculars or spotting scope by a magnet - making it quick and easy to attach. The adapters are great for birding and wildlife photography and videography.
