Everyone knows that the good part of Lucky Charms is the marshmallows. Now, thanks to Tim Lombardi, you can separate the moons, clovers, stars, and hearts from the whole-grain stuff. Lombardi created a cup that he built with his 3D printer that contains holes just large enough for the whole-grain bits to fall through while the marshmallows stay put. Have a 3D printer and want to make your own Lucky Charms Cereal Sifter? Then head on over to Thingiverse to download the specifications.
