Garbage Can painters triangle

I no longer have a woodshop or even a garage, so when I needed to make a boat table I didn't have space for letting my finish dry. I did have 4'x4' is of floor space and a garbage can i got from Home Depot years ago.... so I made up these little triangles to sit on the rim. I always thought these were called bench cookies, but oh well.

After printing, the tip was sharper than I wanted, so I hit it with a file.
