This bracket can be used to reinforce the inside corner of a box, crate, cabinet, or whatever construction project you're working on. The print orientation makes it really strong. I recommend you only use pan head screws with these brackets. A tapered screw head could split the part. I put three sizes of the model in the profile. The small version measures about 30mm deep with a 3.7mm screw hole. The medium version is scaled up 117%, and the large is scaled up 134%.
