In most cases, the impossibility becomes apparent after viewing the figure for a few seconds
These objects are impossible to be made that is till recently…
In this lesson, we will go over how to design and create the impossible object of a cube inside another cube!
After you will get a 3D Printed copy of the cube in a cube you designed and will explore how 3D Printing makes these impossible objects now possible!
