Updated 2/8/2023: Modified the key to make it sturdier.&nbsp;IMPORTANT: After printing, first close the handcuffs to break free the internal latch. Trying to break the latch free using the key may break the key.&nbsp;These print-in-place locking handcuffs also print without supports. I put in a comfortable number chain links to make them suitable for casual wear. That is, you could wear them at a party and still, say, eat and drink. And most importantly, you can comfortably reach to put in the key to unlock yourself. And if you do lose your key, don't panic. The 3rd photo shows the internal latching mechanism. You can easily poke the end of a paperclip or small Allen wrench into the keyhole at an angle and push the latch open.&nbsp;I strongly suggest printing these in PLA with 0.2mm layers (to make the p-i-p gaps work out properly). The print profile provided includes mouse-ear brims on the links to keep them stable while printing. Break these off after printing. (I used to have a print profile without the mouse-ear brims for printer setups with excellent bed adhesion, but too many people were using it - despite the warnings - and complaining that the links failed.)&nbsp;After printing, you'll notice that across the round hole on one side, there is a single layer of wispy filament covering the hole. Use a small round tool or needle file to clear this gunk away. You can also use the pointy end of the key to clear this out.&nbsp;Lastly, when using the key, it only takes a small amount of torque to open the lock. Do not force the key or you will snap it off in the lock and then you will be in real trouble!
