Cubic Sphere / Spheric Cube education and testing (by JuicedCustoms)

thingiverse

This is made from a 40mm cube, from which a 40mm cilinder is cut from all three views. From the front, side and top. So in 2D this is a circle, In 3D it's also a square. XD You can use this to demonstrate that these three round projected views will not necessarily result into a sphere. Can be used as an educational tool to learn and understand the value of projected view in 3D modeling, but also to teach studens a thing or two about the importance and complexity of math. Probably the most useless dice of them all. It only wants to roll in 2 directions. Cool as a gift though. DnD players will probably see the fun of it. :) In the STL this object is positioned on one tip so it will print nice and evenly, however it might need minor sanding and perhaps some paint to become even more appealing. It takes little over 2 hrs to print on the original scale. Enjoy. And keep your creativity going. :)
