Shelf Bracket - Flames & Swirls

My daughter designed this with a pencil sketch to go in her fantasy-themed bedroom. Who am I to argue with the aesthetic?

A shelf bracket for 6 inch (or metric equivalent) shelves. The holes on the wall side are at an angle for easier driving, but this may mean that drywall anchors are less effective. Hitting a stud is recommended. Clearance is given for drywall anchors in the back nonetheless. Countersunk holes for screws into the shelf.

Should print with no support. Heavier walls are recommended if you have heavy things on your shelf.
