Hackers Help: Square metal legs for Besta wanted

I have an IKEA BESTÅ cabinet, 47″ wide. It has currently no feet, other than the height adjusters. I would like to add metal feet, also allowing me to clear the baseboard in the back. I am looking for legs with the following requirements:
– 3 3/4″ – 4″ height
– 1″ square
– brushed nickel, stain, matte looking

The current Ikea BESTÅ legs appear to be flush with the cabinet. Thus would not clear the baseboard in the rear.
I found some BESTÅ legs that appear not to be available anymore:

There are also some general purpose legs on the market from hardware stores. However, I could find one yet meeting the requirements.

Any ideas are greatly appreciated.
