Fatshark Lens Sun Cover

This is a Fatshark Lens sun cover to protect from damage. It uses the slot where the diopter lens goes. These fit pretty well from my delta printer. Not tight but snug enough they don't fall out. I was going to put a tiny piece of loop side velcro under the round end to block more light and give a little more friction fit. They have hole so you can string them together so you don't loose them.

These work with my Attitude V3 AEs and an old Pred V2. Please comment if they work with othe
