Aquarium LED Light Brackets

I have designed these brackets to support a Hygger 26W 24/7 Aquarium LED Light from Amazon They allow access to the top of the water for maintenance and feeding without the use of the original glass lid (removed the glass completely). Our tank is 30" long x 12" wide x 18" tall but the brackets are 10" wide allowing some flexibility in placement. I have included pilot holes for M3 self-tapping screws and retaining brackets, but they fit tight enough to my tank when offset to the back, that I ended up not needing the retaining plates and screws. I have included a sketch of the rim lip that these brackets are designed to fit in the pics. Many tanks are likely similar enough to use these brackets.
