Unusual aquarium decor. It looks dynamic and adds its vibe to the aquarium. It will be a great gift for aquarium owners

is printed in parts and without support. I printed with a layer of 0.25 mm and then glued the parts. Watch the tutorial on YouTube https://youtu.be/02TpRAC12CM

_A cryptex is a portable, puzzle-like container, typically cylindrical, that stores a secret message or items behind a combination lock._


---
This cryptex looks like a Mark 2 hand grenade, with four numbered dials that make up the main shell of the grenade. Similar to [my other cryptex on MakerWorld](https://makerworld.com/en/models/1450159-number-cryptex-configurable-puzzle-container#profileId-1510514), it has ratcheting encoding rings that can be used to set any 4-digit passcode you want! And turning the dials is super satisfying thanks to the ratchet!

There are three different versions of the dials you can print:
- Plain — No numbers at all if you want to paint them yourself
- Inset numbers — The numbers are inset holes on the dial
- Embedded numbers — The numbers are embedded and can be painted in the slicer

If you add a small spring to the fuse, you can make the safety lever, "spoon", to pop off when the pin is pulled, just like in a real grenade!

**Printing tips:**
The parts are already oriented optimally. _Inner cylinder_, _Fuse_ and _Safety lever_ need supports. Use tree supports for the _Safety lever_.

If you're using Orca Slicer or Bambu Studio, a handy project file is included that has my print settings and painted parts ready to go!

**Assembly**
You'll need an optional spring, 0.5x5x25mm recommended, for the safety lever action. But the cryptex works just fine without it, it's just a little fun bonus! You can also use a keyring for the safety pin ring, or use a printable ring.

No other hardware required to assemble! If you have printed the *bolt tool* included with [my previous cryptex on MakerWorld](https://makerworld.com/en/models/1450159-number-cryptex-configurable-puzzle-container#profileId-1510514), it will also work for this installation! If not, the tool is included here as well! Or you can use a flat- or hex head screwdriver too.

See the included assembly guide video!
