I am not sure what your cabinet is like, but I don't think you will need the feet. It doesn't have to be dead on level to work, it is just to keep your fabric moving and not falling in the hole and I don't think it will slide if the top board is "trapped" within the top hole (which means fits wall to wall from front to back) . Note that I made mine to fit the whole machine, not just the free arm so it was easier to measure and cut. Also mine doesn't go all the way accross the back so that I can fit my cone thread holder down and behind my machine. It keeps it from wandering if some cloth catches on it.

In that case you'll probably want to use some sort of leveling feet. It can be a bit of a beast to get everything just right otherwise. With them you just need to attach some blocks are are a little shy of the height you need then use the legs to make it just so. They're widely available in woodworking or hardware stores. The only issue is that most of them are designed to be slide easily and you'll want just the opposite. If you can find rubberized ones that's great, otherwise you can tack a little non-skid rug backing to felt bottomed legs with a little glue.
