The file 'IKEA Lack Enclosure Leg Brace 3D Printer Model' is (stl) file type, size is 2.4KB.
Thanks to @InventorIan for the original design. I'm shortening this to reduce print time and filament without any significant loss of effectiveness by cutting ~60% off the top.
I also scaled this down to ~75% of the original size.
