Secret Box

This model is a box that can be used to hide all sorts of things (money, candy, etc.). It's made up of a lid and a box that can be printed without the need for supports.
If someone tries to open it normally by unscrewing the cap, they won't succeed.
To open this box, you need to:
1- Turn the box upside down, which will unlock a part.
2- Rotate the cap 90°.
3- Put the box back upright.
4- Pull the cap upwards.

Assembly is easy, you'll need the 3D model and a toothpick or skewer cut to 2cm length.
Insert the skewer/toothpick into the lid as shown in the images, then secure the lid to the jar while holding the toothpick to prevent it from falling out. Next, rotate the lid 90° and voilà, the toothpick drops down 1cm and blocks the can opening.
