I have cabinets in my bathroom that were made by Ikea. I got some cool feet that screwed on to the bottom. We re-did the bathroom and put in title, but that meant that the legs were now just a bit too long.
Unfortunately, they don't make the cabinets or feet any more, I don't think. I don't want to throw away my cabinets just because the feet are an inch too long.
So I modeled up feet that slip on over the threaded rod (no threads - might be in version 3). And this way we get a choice of colors!
