You might make a variation of this. Just used the stuff I had on hand for the rectangular tubing.

You can get color matching paint at Home Depot. It's a Rustoleum paint. You'll be able to touch up your scraped paint without a problem. Of course, I made these feet, before I mounted the mill. Fortunately, the PM25 isn't that heavy. The tubing is bolted to the stand in two places for each tube. The tubing is cut at an angle so one can get a wrench in easily. Yes, I had to learn that the hard way.
Once leveled, the mill is very sturdy. No rocking, no moving, no vibration. Looking back, the only thing I would change is the bolt size. Using 3/8". Might want to use 1/2". But I had a big box of 3/8" bolts, (and a lot of 3/8" hardware) so that's what I used.
Your mill needs to be level. You don't want your tooling to roll off and hit the floor do you? But if you only need a 1/4" or so, just use shims. It's far easier. In my case, I couldn't get away with that.
