A simple 4x4 post cap made for wooden posts to keep the rain and elements off the top of the cap.

It's a simple design made to be functional and quick to print. Will fit most 4x4 posts (that are actually 3.5 in x 3.5 in) but can easily scaled up or down if you get a piece of wood that is a little different. The inside is 95mm square, my post was at the most 93mm, so it's a nice fit.

I suggest printing out of PETG or ASA if you want it to last.
