Kobalt Shelf Bracket

I designed this bracket to add a shelf to my Kobalt rack. Everything is pretty tight, which is the way I wanted it. I had to do some very light sanding around the pegs on the main bracket, and I used a deburring tool to clean up all the holes for the pegs and screws. I used 1" (25.4mm) square hardwood and M5-.80 x16 screws from the hardware store. It's probably over engineered, but I want to ensure i will hold a moderate amount of weight. I printed mine from PLA+, but depending on the weight you want it to hold, a strongermaterial may be better.
