This design is a submission to the Tinkercad Halloween competition, sponsored by BCN3D.

With these teeth, you can use them to decorate your jack-o-lanterns and make them a lot spookier. If you printed them too small and can't get the stub on the teeth to stick into the pumpkin, you can apply some glue (I would use superglue) to stick the teeth in it. Keep in mind that the smaller teeth on the side should be used for the back of the pumpkin's mouth.

The design can be viewed from Tinkercad from here.
