My "OLD MAN" eyes have a hard time seeing the Elegoo Saturn Resin Printer screen. So I designed this to hold a small magnifier screen. I used these: https://a.co/d/h4HzKs9 from amazon. 12 pack for under $5. After printing, just hot glue 4 small magnets on the legs. Or double sided tape it. I like the magnets, because I can pop it on or off my Saturn anytime.

I printed it standing on its end, with the slot up. So no supports or bridging would be needed for the slot.
