I turned the icon art for the Kulu-ya-ku into a 3D object. There's two versions you can grab; either with a flat back or with some hollowed out areas. Besides it saving some material, I use the hollow areas to put in some magnets so I can easily attach it anywhere I like (as long as it's metal).
The hollow areas are 1/3 of the total height of the object, so if you also want to add some magnets, measure your magnets to know how high you should print for a perfect fit!
You only need supports if you use the hollowed version.
