Designed this for a buddy wanting to use his phone to look through a set of binoculars. Attach the coupler around one of the eyepieces and tighten accordingly. Need to make a plate with magnets to attach to your phone, then this coupler will magnetize to that plate and attach to the binoculars. That way you like can align the camera on your phone to look through the camera.

Rare earth magnets from Harbor Freight for $2.99.

Printed in TPU for flexibility but print it however you want.

v2 has the slots for the magnets on the side so you don't have to glue the magnets in on the bottom.
