Keter Shelf Support

We recently purchased a Keter resin storage cabinet. During the assembly process the tabs on the shelf center support broke. My wife asked me if I could make a replacement part for it rather than wait for Keter to ship one to us. I removed an already installed support and one of the two tabs broke off of that one as well. I believe this is a weak point in the design. So I decided that I could print a piece that is stronger than the original. I designed this in Fusion 360, sliced it in the latest version of Cura, and printed it on a Creality Ender 3 Pro first gen.

I don't mind anyone remixing this, but would appreciate a reference to this original file. Feel free to let me know if you use this and whether it works for you. Tips are not at all expected, but will be greatly appreciated if given.

I printed this model standing on its side as shown in the photo so that the "short grain" is not running along the width of the tabs, rather the layers are running perpendicular to the stres
