This is a nutcraker that I designed.
It consists of two pieces and works just like a skrew.
It works pretty good for hazelnuts and walnuts.
In order to use for bigger walnuts you should skale it by 120%.
You should choose a rather high infill to make the nutcracker stronger so that it does its duty without deforming or breaking. I printed it with 60% infill and it seems to work pretty good.
For the base, part number two, you can use supports depending on how good your printer handles bridges.
I tried it both with and without supports and it worked either way.
Althought it came out slightly better with supports.
