Shelf Bracket for Heavy use

-I made it for heavy use (holding 6 inch or wider woods as a shelf).- for any outdoor or using in warm places, use PETG at least.-any drywall screw or self tap can be used. the model screw holes are 8mm (head) 3.8mm(body)-if yours is heavier increasing the infill is a good option.-descaling should not be major problem unless using smaller screws
