These feet are for the Home Depot brand HDX plastic shelves seen here:

The unit comes with 5 shelves and 4 feet, but you need more feet if you want to break it into 2 separate shelving units. I have 3 shelves in one area, and without feet the other two fall apart.

These will probably fit other models of similar shelving units. I'd suggest checking the measurements in your slicer. Maybe partially print one to make sure the diameters are correct, then adjust.
