Printable Handcuffs v1.0 by gianteye Nov 14, 2009

Description

So you've gotten your hands a handcuff key to print in case some vagabond cuffs you to a table conveniently within reach of your trusty Makerbot. But what if, using your newfound freedom, you find yourself at liberty to turn the tables and show them what the powers of nerd rage, extruded nylon filament, and Greyskull combined can achieve? This is a functional pair of handcuffs that you can print out in the comfort and privacy of your own home.

Ferret7 printed one out! thingiverse.com/thing:1300 Awesome!

I just polished off a working model. Take a look here: flickr.com/photos/gianteye/sets/72157622866071790/

I hope it's me but the small parts don't come out the right sizes, they're all too tight. The lockpin was too tight, too big and too short. The toothweel was too tight and too small, too. Using Makerware and a Wanhao Duplicator x4. (note: with ABS the cuff itself also moves enough to come loose of the toothwheel, maybe introduce a guard?)

What bed material are you using while printing with nylon? Have tried a few different materials and temperatures but I don't get it to stick well enough.

It's gonna vary from machine to machine and even between different build materials. I think I got luck with this one eyeballing the threads from other designs.

I've fantasized about living in a world with a searchable database of materials and engineering standards for easy reference. Getting the minimum thickness and step without shrink in glass filled nylon injected plastic would be useful data.

Instructions

Download the RAR package. All the parts labeled "a" are arranged to print together. The same goes for all the parts labeled "b". Print two of each set and you'll have a complete pair of cuffs. I've also included the parts separately.

Once again I can see the need for a printable "standard" which we could use to test print threads and fasteners in general. I know I can/have printed threads - but there is a size and shape limit.

VERY cool! Will it be compatible with the (printable) Dutch/German key (STL available online)?
See http://blog.erikdebruijn.nl/up... for more info in that :)

I hope to print this very soon. 8-)

Didn't Vik suggest that we should make sex toys and make 3D printing popular for a wider audience just like the it did for the internet? He might have said something different... ;)

I believe that @ home sexfab would increase the stickyness of reprap and makerbot. I alluded to that very key in the description to this project. I'm eager to see if it performs like I'd planned with the reduction of resolution that desktop printers provide.

Well one of the neatest things I've printed so far ! many thanks :)
BTW - it is so well designed that I didn't need any tools for assembly
(I need to get cracking with SolidWorks to see what I can come up with that is equal to this)

Well THAT's cool.
How many people have printed this successfully?

Next step: an open/translucent 5-pin lock for lockpicking-demonstrations.
