It’s a dorky chemistry joke and it’s a pun and it’s an egg. It’s like it was made just for me. Thank you, Thingiverse user linuxwrangler! Pictured is diethyl ether, which is what most folks are talking about when they say “ether.” But the C-O-C bond is really what makes an ether, and there are infinitely many possible alternate ether eggs if this one does not satisfy your new craving for them. I am personally holding out for the fluoromethyl hexafluoroisopropyl ether egg.
