Introducing the (already existing but made into 3d) missing square illusion!

After being inspired by Michael Stevens' Missing Cookie Illusion, I thought “huh, why can't i find this as an STL anywhere? It's all that one triangular missing square illusion!"

So I  hopped into fusion and quickly whipped up this model, and here we are: the Missing Square Illusion.

WARNING: You will have to scale this up a lot in your slicing software, I forgot to do it in fusion.

Instructions to wow your friends: Take model off build plate. Remove middle square. Rotate large squares clockwise twice if you want the square removed. Rotate clockwise twice again to have the middle square back in its place.
