This is a Square

Yet another model born from the fact that somebody showed me, a person with engineering skill a 3d printer and OCD, a meme. I will be honest, when i saw it, i didn't believe that the shape was mathematically possible… But it is! A Square, as i was taught, is a shape with four sides of equal length and four 90 degree angles. The the arc length of the two arches and the lengths of the two straight sides are all exactly the same. Furthermore, each end of the straight lines intersects the arches at 90 degrees of tangent. Behold the Square. Boost MePlease consider a boost. It helps buy filament which i use to test new things, create prints to display at 3d printing shows, and make things to give away to kids.
