Nut & walnut cracker [My grandma design]

3D model description

Another one of my designs I have been using it for ages. I was trying to design this plastic one the same as the wooden one I found in my grandma's house. The best part is that the shell is not flying around when you crack it. There are two designs: small for nuts and big for walnuts&nuts. But lately, I am using only the big one.

Thank you, grandma, for a beautiful design.

The models in the pictures are made of PLA and 0.2 resolution with 20% infill. The base needs only 20% infill because the entire shell is made of small cylinders which significantly improve the strength of the material, see the last image. The handle must be printed vertically.

What material and density did you go with?
