I needed to crack open a load of walnuts, and wanted to continue learning to use Fusion360, so I designed this nutcracker as a solution to both!

It's shaped like a mushroom because it's fun.

I printed all the pieces with 4 perimeters and 25% infill and it seems plenty strong enough, although I would consider printing the small cap that fits on the screw at 100% infill as it does take the brunt of the compression force.
