Reflex Sight, sun shade

I made this to fit the cheap Chinese made Reflex Sights you see on Amazon, specifically the one in the link below.
to help reduce the reflection you get on the shooters side of the sight, when it's very bright out.
Worked fine, until i lost it on my last range trip. I only use it on my kid's 10/22 as that sight will not hold zero very well on anything larger.
Soon as I print another one, I'll post some pics. If anyone makes it, please post a pic.
Thanks
