Since the first “public appearance” of 3D printers I’ve been thinking about using them in any fetish/(self)bondage activity. But nothing except dildos or any other insertables comes to my mind. And even in this area my imagination can not compete with what’s already available in silicone, latex, plastic or even glass.
Fortunately we have more creative persons around! Remember the self-bondage leotard? Petrolio designed and printed the rope lock! See a couple of photos below and check this forum thread for more information: Self-bondage unitard.
Any other ideas?
