Ornamental cap for top of 4x4 deck post. My original caps rotted. I designed these to match the style of the original caps, printed in a light color (PLA), painted with deck stain, and glued them on top. They've been in place for over a year; so far, so good. Nobody can tell they are plastic. If you aren't painting them, you should probably use PETG or something better than PLA for UV exposure.
