These cutters can be a fun way to teach numbers to toddlers, using play doh or by baking cookies. They could also be cut out the shape of multiple digit numbers.

If using for baking foods, I recommend looking into the safety of the print materials you use.  I printed in PLA, which I believe is safe, but you can also take the extra step of using a food barrier, like cling wrap.  I believe this would also lower the risk of contaminating the food with any bacteria that may reside in the layer lines of the print, beyond the reach of a regular cleaning.
