About this model

This is a really stunning illusion :-) Depending on the way You put Your fingers, the turn of the coin results in different directions of the arrow from the back side! Because I only have a mono 3D printer, I decided to create my own version of this coin. I also added spikes on each of the 8 corners, so the coin can be easily turned between the fingers. There is no need for any support. Have fun :-)
