Here are some models of a knife, spoon, and fork.
with the exception of the knife, these will need support material.
Solidworks files included so you can make changes.
i believe these are the first of their kind at least on Thingiverse. hopefully these will inspire others to create different models as well!
They turn out to be fragile when printed. I will eventually update the stl's to create more robust utensils. the knife is almost at that point.
Enable support, and print. 100% infill is probably preferable.
No guarantees on the safety of plastic, so use at your own risk! In general, use PLA, and do not use with hot foods!
