Flexible Handcuffs (Dual Lock Design)

thingiverse

I wasn't satisfied with the other handcuffs I could find on Thingiverse, so I designed this one to suit my needs. All of the other cuffs I found were made from PLA and required assembly after printing. Trying out those designs, I discovered they were a pain to assemble and, more importantly, uncomfortable. Thus, I designed this handcuff, which is made in a single piece of flexible filament (I recommend NinjaFlex) and can be worn or used for much longer before becoming uncomfortable. Hopefully, in the future, I will have some updates with small tweaks to the design. The cuff diameter is 50mm, making it suitable for smaller wrists, although scaling it up should be fine, as it would make it more comfortable due to increased bend zones. Cuff diameter: 50mm Time to print: 5 hours Final weight (without locks): 32g (6% of a standard NinjaFlex roll at 500g) This work is licensed under a CC-AT-SA license. You are free to remix the design, and even sell prints of this if you so desire. I would ask that you let me know if you do, as it's cool to know, though you're not obligated to. - May 21st, 2018: First version released - June 12th, 2018: Updated version released. This should be almost identical to the first version but with two noticeable changes. The inside of the cuffs now tapers on one side for increased comfort. It doesn't taper on both sides because of bed adhesion and overhangs, so be aware of which side is up when putting it on. The locking holes are inset more, giving it more structural rigidity. These are just the changes that are easily noticeable. Behind the scenes, I've completely rebuilt the model to accommodate more cuff sizes and variable distances between the cuffs. With this done, I'll post more variations on the design for larger or smaller wrists and larger distances between the cuffs in future.

Donations are of course optional but they help me allocate time to update designs and fill feature requests.
