Combination Safe 00 (Cryptex)

DESCRIPTION:
A five or seven character cryptex that can be used as a small safe / money box and is ideal for storing small valuable items that need the kind of security that only comes form a pocket sized safe made of plastic.

Enjoy!

KEY FEATURES:
• 100,000 or 10,000,000 possible combinations for the 5 ring and 7 ring versions respectively.

• Each ring can be set to a custom number and can be changed at any time, by anyone possessing the combination to unlock the cryptex + Locking Tool.

• If you wish, you can design your own custom combination rings with this, easy to use OpenSCAD file: Outer Ring Customizer (OpenScad).

• Sturdy construction. Unlike many other designs, this one features a locking component that holds the cryptex together even when open, thus stopping it from fall apart while in this state.

• Easy print. Designed specifically for the 3D printing there is very little by way of overhangs and thus no support structures are needed. Theoretically the parts should require no cleaning and can be assembled strait off the build plate. All .STL file have already been rotated for best print results.


IMPORTANT NOTES:
1) Although there are no support structures to clean up i have fount, on account of the components being a naturally snug fitting, even small imperfections in the print can cause parts to become tight or catch. So keep the craft knife or sandpaper on hand just in case :)

2) I have created a couple of remixes of this design that you might also like to check out:
