Strong Angled Wall Bracket \ Art Hanger

I needed some hangers to display this kumiko panel that didn't distract too much from the design, but also strong enough to support it. I designed these hooks. They can accommodate frames up to 20mm thick. There are countersunk holes for 2 standard size 3-4mm shank screws or toggle bolts for redundancy. The hangers are angled backwards 8 degrees so that the artwork is able to lean back a little against the wall and doesn't fall off the wall easily. Please print in this orientation. The laying on it's side orientation produces the strongest part. Add as many walls to make them stronger if desired, but they're pretty strong as is. Boost MeAny boosts are greatly appreciated!
