A really clean and simple & strong strap-type shelf bracket system I've designed, with a neat dovetail cleat mounting system for a clean mounted look. This is a strong & simple model to print.
Use 12mm beach plywood of width 195mm (any length; I've spanned my brackets 500mm apart).
Printed in PLA with supports on for the main bracket (due to the overhangs in the dovetail).
Use standard 6mm x 60mm expanding Fisher bolts or 6mm countersunk screws.
