Everything Cryptex

Yet another cryptex. I couldn't find a printable cryptex with all the features I wanted, so added everything I could think of.

### Features include:

- All parts are customizer-enabled for customizing the dimensions (internal length and diameter), number of rings, number of positions, and the letters/numbers/whatever on the faces of the rings.
- Changeable code without reprinting.
- Detent mechanisms, so rings snap into place and "click" when turned.
- Resistant to "picking" by feeling for ring resistance.
- Snaps together so it doesn't fall apart when unlocked; requires a bit of force to unsnap and change.
- Glue not required, except for the optional decorative end caps.
- Locking ring cannot be disengaged while cryptex is locked, preventing forced disassembly without unlocking.
- Designed for easy FDM printing; no slopes or overhangs greater than 45 degrees.
- Minimal number of parts; no extra pins or springs needed.
- Tight clearances for solid feel. Outer label ring
