When installing Gutter Guard-like products, sometimes the gutter has been deformed a little and the gutter cover doesn't reach across to the little rim that's provided, which is supposed to hold up the house-nearest edge of the guard product. This support bracket takes the place of the rim in holding up the guard.

Made in Tinkercad. The 3mf and the gcode print 4-up, the STL is a single support.

They don't have to be super strong as they don't get a lot of load, unless you have trees falling on your roof, in which case you have other problems. Print in PETG as PLA will eventually be dissolved by the rain :-)

Revised 2023-11-08 to remove non-needed radius on inner bar.
