Today I’ve seen some ads while browsing in the internet about Foreverspin (I don’t know really why). I saw that it’s a kind of special cool spinning tops made in some materials (stainless steel, gold, zirconium, tungsten, etc…) and the tops cost even more than $100! So I took an image with the profile curve and I made it in Rhino 5.0. Now, you can download it and 3D print it! :)
