handcuffs and collar with joining bar.
i havent printed it yet as i keep getting interrupted. (3 months since i designed, havent had any time with no one around)
once i finally manage to print it, i will fix any problems i find in it

the lock used is based on the lock from https://www.thingiverse.com/thing:2053930.
i have completely redone it as that is way too small for my wrists

the skp (sketchup) files are also included
