No assembly required, no supports needed, shapes can be re-scaled in slicer to bigger sizes, as well as cutter height, for thicker cuts.

I thought this would be a good tool to teach shapes, as well as sight words, through play 

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.
