The magician takes out an Oreo, place it in his mouth and bit off a piece to taste. Then he puff the bitten piece back to restores the ​cookie.

Trick is repeatable, simple, and fun for children.

You will need to glue 2 printed half together, then place a tight rubber band to hold the full Oreo together.

I included few designs, one I tried to have a full Oreo without the need of gluing 2 half's, the result looks good, but unreliable as the rubber band keeps snapping off. (maybe there is a way to design it appropriately using supports)
My current option is to print a cookie twice then glue to each other (this allows the band to hook and keep the Oreo from snapping off) .

update, just added a ready print file of the cookie with support, no need to glue two pieces, you will need however to remove the extra filing in between (with knife)
