Shelf Support Bracket

Remixed from andrethomas' bracket. Rounded the back corner and adjusted the holes to fit coarse drywall screws. Includes 105, 125, 150 and 175mm versions. While profiles for PLA and PETG as provided, I prefer PETG for the added strength and to avoid material creep. Also note that these have not been tested to hold any particular amount of weight, so use some judgement on how these are printed and how much weight you subject them to.
