Modified Mr. Potato Head glasses that actually stay on!

I designed and printed this with nylon, 100% infill for a sturdy replacement for my son's Mr. Potato Head glasses. He is quite particular when it comes to his Mr. Potato Head toys (he's something of a connoisseur) and always got frustrated when the included glasses would fall off. So, I designed these and they work much better (and the other pair mysteriously disappeared when he was napping one day!)
