My first items will be facial features (like Mr. Potato Head eyes) for my pumpkin, a peg tray to hold the rubber ducks in my friends jeep, and a tiny trash can to put on my nightstand for contacts and their packaging. I thought these silly things would be a good place to start because it doesn't really matter if they're completely right. Once I get the hang of it, I'm going to make Braille Play-Doh presses for work and brackets to hang drills in my garage. By Christmas, I would like to be able to make custom ice cube trays for friends and spiral notebook covers that say funny things for my coworkers.

Obligatory reminder that 3d printed objects are not food safe without specialized coatings/finishes; even then I don't know that it would be safe with the temperature changes of freezing and thawing affecting it's structure.

Genuine question: is this is "only" about small gaps between layers where bacteria can grow or also something else? E.g. I always assumed cookie cutters are safe because a) the dough is heated afterwards, so potential bacteria are cooked and b) they are rarely used, so they dry completely out and the bacteria, too.
