Binocular eclipse filter for 50mm welding shade

thingiverse

This is a dual-part, threaded filter holder designed specifically for binoculars. It securely fits onto the end of the binoculars via friction and accommodates a 50mm welding shade filter. I created this holder tailored to my existing Bushnell Falcon 7x35 binoculars. Although I'm unsure if these are the ideal binoculars for eclipse viewing, I wanted to give them a try. The holder is not universal but can be easily modeled using Autodesk Fusion 360 and its threading feature, making it an excellent example for creating customized holders for different binocular models. Simply draw two cylinders and add threads, then you're ready to go! The 50mm shade filter is secured by a 48mm lip on the end of the threaded outer piece.
