I was inspired by this video from Makers Muse:

I wanted a box with a similar mechanism, but simpler and smaller so the box does'nt take 24 hours to print. So I made my Fancybox!
By turning the knob on top, the wheel spins and pushes the locking-pins in and out with a satisfying action.
I plan to give them away for christmas, filled with cookies.
I printed everything with the DRAFT preset at 0.24mm layer height (and lowerd infill for the box) on my (modified) Ender3. Tolerances are rather generous, if your printer can do 0.2 mm tolerances you'll be fine.
