I used PLA to print it. Just make sure it's lying flat on the build plate in your slicer, so you don't get odd messages. I was able to print it without supports or any build plate adhesion extras. But it probably is best to have a heated plate. And the one you see in the picture, I scaled it longer, along its length while in the slicer just to make it taller. I'm thinking of printing some in brown filament too.
