Chastity Cage Locking Pin (using handcuff key)

Inspired by the New Fun Chastity Cage Hinge Pin but built completely from scratch. The design is based on an unbranded cage purchased from Amazon. Use a standard handcuff key to rotate/lock it once in place.

The dimensions (diameter x length) for the individual segments of the pin are as follows:
- Cylinder+Taper: 6.28 x 18+4.5
- Dowel+Tip: 3.0 x 3.0+0.5
- Locking Tab: 3.0 x 6.0>5.25 (from centre of cylinder)
- Key Way/Peg: 3.68/2.68 x 3.75
- Key Flag: 1.0 x 3.5 (from centre of Key-Way)

The tolerances used for the handcuff key way are *extremely tight* to preserve as much material/strength around it. Regular PLA - at least when it's printed on the hotter side to improve layer adhesion - appears to be up for the task. The key way likely won't tolerate much poking around though so I advise against trying to unlock it without a key. ;-)

My Smith & Wesson key is an exact fit; it slides in with minimal resistance and lightly holds onto the pin. You may need to adjust the
