A low poly triangular shape I designed to act as a buoy style wind chime sail. It stands at about 5.9" x 4.88". It worked great and ended up looking rather nice, so I created to place on my desk. This is the original version that includes a small 6mm hole near the top for a carabiner clip. I've also uploaded a separate version without the hole if you're interested.
