Toolbox Feet to Replace Wheels

I created these to replace the wheels on my new craftsman tool chest (CMST22751RB) to lower it to fit underneath my workbench. It is now about 29.375" tall vs the original 37.5" with mounted wheels. These are necessary to bear the weight of the toolbox instead of letting it rest on the thin metal edges. The 4 screw holes are on a 3" x 1.75" pattern
