Telescope Red Dot Finder Rear Sight

I made this to act as a rear sight for my telescope's Red Dot Finder used to point the telescope at an object of interest. I was spending much more time than anticipated just getting my head into the very narrow cone where the red dot is visible. This simple rear sight has DRAMATICALLY reduced the time and frustration using my scope's stock pointer. Place it about a foot behind the Red Dot Finder and hold in place with a 6mm magnet. Tinker height to match your scope if necessary. Base is designed for 130mm tube. This is also a public file on TinkerCad for ease of remix.
