Angle bracket with screw hole

I have these IKEA boxes for my son's toys and their bottom plate is held by these small metallic brackets, however with usage they had gone a bit loose.

So what I did was design the same type of bracket, but longer to make sure that it always keeps the bottom plate in place.

I also wrote about the process here: https://blog.georgi-yanev.com/projects/solving-problems-using-3d-printing/
