Self-bondage handcuffs

thingiverse

These handcuffs empower individuals to experience self-bondage with greater ease. With deliberate effort, users can expertly tie themselves behind their backs using these very same cuffs. The ultimate locked-up sensation is achieved by utilizing a timer-lock feature. I haven't personally experimented with the modified versions, but I recommend utilizing the inner and outer pins to create functional hinges. To secure the cuff firmly onto your wrist, employ two M5x20 screws and 2 M5 nuts. Once secured, slide the lock through the carefully crafted holes and engage it – effectively locking yourself in place. For added safety, consider leaving a small margin of adjustment on the nuts to ensure an emergency release is possible if needed.
