hand cuffs adapted for hardware

i enjoyed the original design but wasn't a fan of the nuts designed for it. so i tweaked it in tinkercad to allow the use of normal hardware, the holes are 4 mm wide so any bolts smaller than that will fit. now your cuffs wont fall apart during activities. print 100 percent infill for a pretty strong pair of cuffs. the tolerances on the holes in the top piece are pretty tight, so reaming them helps make a nice press fit.
