Squirrels had their monopoly long enough: Now you too can stash acorns! Your could probably even stash an acorn in your acorn, if you so please.

Please be aware: The thread is left handed as opposed to the right handed thread you are used to. I did this as an added security measure to keep nosy people (and smart animals?) out of your very own acorn.

I recommend printing the top with the fuzzy skin setting but who am I to tell you what to do?

Can use supports but not needed if you're comfortable with your printer's bridging ability.

Update: Strengthened the anchor point a little because it seemed too weak for my acorn needs.

Upupdate: Added step file.
