Simple Shelf Bracket

I liked the design from oomagnumoo: https://www.thingiverse.com/thing:1691108.
However, I did not plan to do woodworking, so i created a new bracket that is heavily inspired by oomagnumoo's design, but can be mounted to a wall with a screw. There is a version with a hook and one without a hook on the bottom - if you wanna hang something on the bracket, use the one with hook.
Hope you guys like it. I used 60% infill and white filament. Have no wood filament at home but i am curious how it would look like. If you print it in wood, please leave a photo :)
