James Web Space Telescope camera shield

So created a James Webb Telescope mirror setup in my classroom. I used mirrors from Amazon and the kit is around $10 USD.Here is the Amazon link: https://www.amazon.com/gp/product/B09722MG6SSo the middle of the scope has a black box unit where the camera is, so I made a basic shape so its more 3 dimensional on the wall. Used hot glue gun to adhere to wall.Its not to any scientific scale, just the same general shape.Post pics of any makes please!
