It's an icosahedron! I made this for a friend of mine, and I thought I might as well share. I don't think there's an icosahedron that's hollow already up here.

I'll upload my source file too. This was a fun object to model, because it can be constructed with three perpendicular golden rectangles.


I sliced mine at 50% scale, and with 0.4 mm layers the walls ended up being 3 extrusions thick, which was just about right. Of course, the top will need to be bridged, so make sure you've got your temperature and feed rate settings calibrated or it may droop!

Your model was one of the first things I printed when I got my 3D printer, several years ago. I printed it in translucent blue filament, and it's beautiful. When I do my workshops on 3D Printing for Teaching and Learning, I always pass around your model. It is striking and immediately grabs audience attention. It's also a great example of fill because they can see the fill pattern inside the hollow object. Your model quickly connects with math instructors too, and they definitely see the value of 3D-printed objects in their classrooms after they see your Icosahedron. Thanks for making it available on the Thingiverse.

Thank you! This is the shape inside the magic 8 ball.
