Handcuffs

Please excuse the bad 3d printing job. My PETG isn't very good (the purple PETG) and it wasn't completely dry.

I used the following to make these:

* Purple PETG for cheekplates and spring.
* Black Carbon Fiber PETG (3DXTech, much better than the purple that I have) for shackle and pawl.
* Blue PLA+ for everything else (could be other materials, but I didn't want to reprint anything. The double lock bar should be of something somewhat flexible though.)
* 14 M2x20mm flat head screws
* 2 M2x16mm flat head screws for key pin
* 16 M2 nuts
* 2 M4x20mm screws
* 2 M4 nuts
* 1 M4 swivel such as [this](https://www.amazon.com/dp/B07FKDSLSM?psc=1&ref=ppx_yo2ov_dt_b_product_details).
* A metal handcuff key, of course. :)

I didn't use supports on anything except the shackle to preserve the chamfer at the end.

You'll need to mirror the parts in your slicer to make the other cuff.

I plan to redesign these so that the swivel can't be levered against the retention mechanism
