3D Printed Handcuffs
3D Printed Handcuffs
STL files for these cuffs are available at Printables and can be found HERE.
This is a pair of realistic Handcuffs I designed for fun. I designed them just from looking at a picture I found on the internet. They feature a button activated double lock. After activating the double lock you turn the key in one direction to unlock the lock then the other direction to unlock the actual cuff.
This is the design in CAD.
They are printed full size in eSun PLA.
The layout out of internal parts. I used (3) pieces of 1.75mm Filament x .40″ long for the pins and I tapped the holes with a 4-40 tap before inserting the screws.
The chain and swivels are printed as one piece with supports as shown.

Thank you for this fun project. I did print them and found as your Note said – “With the double lock engaged it is supposed to keep the cuffs from tighten up but with the inherent flex of the bow from being made of plastic it can still tighten if forced hard enough.” I found an easy fix for this was to add a square section “ridge” on the handcuff casing and handcuff face and a corresponding groove on either side of the handcuff bow. The ridge and groove are sections of a circle with the center being the bow swivel point on the handcuff. I can send STL files if you wish. With this modification the double lock works correctly and makes them safer for play.
Yeah send them over to my email… I think I see what your saying but it will be easier to visualize with the STL.
