I have seen in videos some puzzles like that and i wanted to make my own. So I designed that :).
Spring for pin is 5mm diameter and lenght about 13mm. But as this spring is random old spring from my drawer, you should find yours lenght by combressing. It shouldnt press too hard and pin shouldnt get stuck too.

Yes

Notes:
I used 0,15 resolution for thtreaded parts. Supports are good to use for outer housing, that has labyrinth. Yeah, its annoying to remove it from inside, but its worth it.
