Vortex Puzzle Box || Print-in-Place

This print in place puzzle box isn't very complex with many steps, but the solution is probably interesting and unexpected for most people! Can you solve it?

If you want to see how to lock it and spoil yourself on how to unlock it, watch this short video: 

After printing, make sure all four pins are moving freely, as in they will move their full range of motion just by tilting the box 90 degrees.

To lock the box, align the front of the pins in the lid with the edge of their holding block. While keeping the lid upside down, rotate the box to the lid. Shake the box around. The box should now be locked. Now how do you open it?

There are two versions available; decorated and plain, if you want to paint and/or decorate it yourself!
