Strong 10kg Shelf Bracket Pair

I designed this bracket to hold a new shelf I installed in my garage. The shelf is custom made by joining three leftover pallet wooden planks. InstallationEach bracket has two holes on the backside (you can see them in the rendering). I used a pair of 5mm diameter x L50 carbon steel dome wood screws, which I installed into the wall at proper distance. Then, the bracket simply slides onto the screw caps and the weight of the shelf and the bracket itself pushes it down and locks it in place. See picture on the side for reference. Make sure to identify a stud in the wall to install the screws. It will make them hold much better. DO NOT INSTALL on dry walls or plywood directly without a stud support.MeasuresThe bracket is designed to hold a 2cm thick shelf. There is a groove on the backside, which will accomodate a 2cm plank and prevent it from moving up. I provided the step file in the project so you can load it into a CAD program and change the distance between the top of the bracket and
