Nutcracker

Nutcracker with conical chamber

The print takes 7.5 hours and around 125 grams of PLA

Works OK-ish for cracking walnuts size 35mm and for almonds.
I printed it in PLA but has some flex to it. If you print it from something else please tell me how it went.

You will need to sand the axle a little bit because it is too snug.
You can add spring: the pockets are for 4.5mm (I took one from automatic pen)
