A full length dew hood for a Telrad reflex sight finder. Helps keep dew off of the glass on both sides when mounted to your scope, entirely passively. I made my own version after trying another that I felt could be done better, so this is a thinner (but still plenty rigid) design that covers the full length (but still fits on a standard Prusa i3 mk3 bed) of the finder, prints without supports (top face down on the bed), and snaps securely in place - no rocking or sliding around, but still removable.
