Geocaching Container - 3D Printed, Lockable With a 4-number PIN

I like geocaching. If you don't know what geocaching is - https://www.geocaching.com is a good place to start.

I've also purchased a 3D printer recently. After printing multiple maze containers for geocaching, I've decided to dust off my basic engineering skills and chose Tinkercad to make a lockable geocaching container.

So, I present you the 7th attempt at box making :D

First versions were .... emh... not a box... or not lockable ... or consisted of like 20 parts (yes, really) .

The lock is a rotational thingy, which is glued to the numbers' wheel while rotated to the preferred symbol.

The attached files should be quite self-explanatory, also a few links to the files online:

Supplies

3D printer. I used Creality Ender 3 Pro with 20-80% infill.

Step 1: Printable .stl Files

Printable files, separate for the lid, box (+ unlabeled box) + the locking mechanism made out of two parts - a locking wheel and the numbers' wheel.

If your print feels too loose, you might print a few of the 1mm spacers and fit them between the lid and the numbers' wheel.
