i am lost i am not sure how to hold it to see the Illusion

It only really works if you close one eye, otherwise stereo vision makes it obvious to your brain that it is being fooled. Hold it with the spiky part towards you. It also works well when taking photos of it.

i figured it out pretty cool thanks

If I print this at 200% scale with the "near" file will it still print OK?

Yes, but you will need to look at it from twice the distance to see the effect.

Thanks! What is the normal distance? Meaning how far away would one need to be to see the effect without scaling?

For ‘near’ it is about 25 cm, for ‘far’ it is about 33 cm.
