Looking for a good STL that will help me test part fan cooling ideas. Something that prints quick. I don't want to take hours to test my ideas.
Thanks!

I like the hollow pyramid. It's quick to print and I can see on the backside of the pillars if the cooling is working well. I have 1 fan right now and can tell with the pyramid I need a second blowing at a different angle.
