I can’t claim this as my original idea. I saw it somewhere sometime in the past.
[EDIT] I found where I got this idea. It was in this video tip by Chad Stanton.
It’s a great idea though and uses up some small scraps of plywood. You can buy paint pyramids, but I like the free option. All I did was take pieces of 1/2 inch plywood and cut them into approximately 2×2 inch squares. Then I drilled a pilot hole and made a countersink for a deck screw so they would sit level. Make sure you use the same length screws for them so they match.
You can see I made a mess of them.
Here are the commercially produced variety in case I’m speaking gibberish:
