China Beamer ceiling holder

So i got this Mentech beamer from Amazon and did not find a ceiling holder to buy. I created this model to find a solution. The beamer slides into the side with minimal tolerances. I added 2 holes for screws so it should hang safely or just use a superglue if there is no tapestry. This dimensions of the sliding in are for 104mm beamer with 6,5mm thickness.Here is the Beamer : https://www.amazon.de/dp/B0DGSMGXGZ?psc=1&ref=ppx_yo2ov_dt_b_product_details (No affiliate link)Edit : A friend of mine bought a cheap beamer on Temu. It also works great for it, but the little recess don't fit so great for an “anti rotate” so if you dont touch it, it will work fine.
