Do you like magic? I am a sucker for a great party trick or an illusion that melts my brain into submission. I found this model on Thingiverse and easily printed it without any fuss. I did notice that there was a gap at the bottom of the model that I was unclear of its purpose. The fix for the strange gap that I found is to sink the model down into the Z axis so that the gap sits just below the plane of the print bed.
I scaled this model up 200% and it printed beautifully. It looks as if the scaled up version has a better illusion effect.
To make the illusion pop the best you can set it on a table and rotate it until it looks most like a circle or square, then raise or lower your head to adjust your eye angle until the illusion is most strong. You can also adjust the distance away from you that the print sits. You will quickly find the best combination of distance and angle to make this illusion the strongest.
For an even more crazy illusion set a mirror up and you will see both sides of this tricky print at the same time!
