Penrose triangle like figure

Also called "impossible triangle". I made this fast design, inspired and referenced by the Antichamber videogame logo. The Penrose triangle, originally designed by Oscar Reutersvärd, as conceived is impossible to make as a physical solid object. Every single way to depict it is an optical illusion, including this one. My model looks like one of these triangle only in orthographic superior view. I made also a "flat" version for easier print. However for any of these versions I recommend not to print it in the obvious way, but tilted 90°, because this can make the layers more visible. You will need of course a lot of support.

I spend part of my time making these models, letting them available and free for everyone. If you want to support my work, you can contribute with me here:
