Nut cracker

This is a versatile, heavy-duty cracker designed for printing.

I’ve successfully used it to crack walnuts, hazelnuts, and pecans with this design.

It’s also great for cracking crab legs and other hard-shelled seafood!

The best part is, it’s made to be printed with PLA.

For tougher nuts, like Brazil nuts, or other very hard items, consider using PETG for printing.

Once your model is printed, simply remove the supports and give it a firm squeeze to free the hinge.
