I made this holder for the Reveni light meter which is optimized for quick, one-handed operation directly off a lanyard. The front cap is meant to keep potential fuzz out of the sensor and it stays in place thanks for a small registration pins. A piece of standard 1.75mm filament is used for the hinge. Simply push the filament from the side which has a wide enough opening while the other side narrows down so the filament stays in place via friction… then cut off the filament which still sticking out.
You will require a fairly thin lanyard for it to pass through the hole.
Ofcouse this holder/case can also be used without a lanyard if all you need is a compact solution for protecting the sensor and for comfortable holding.
