Threaded wrist cuffs

Before the invention of the modern ratcheting handcuff, “Bango” style cuffs were the most common type of handcuff used in the United Kingdom. The wearer's wrists go in the two U shaped slots, and a screw is turned on the center thread to lower the arm down onto the wrists. My 3d printed version functions exactly like the historical version, and fits almost any wrist size, from very small to very large. This design is meant to be easy to print and not require any other parts. The bottom of the main U piece is flattened, it only needs a bit of support material on each end. The screw threads function at 0.2mm layer height, and if you want them to thread very smoothly, consider 0.16 or 0.12 layer height. The default included arm has a flattened top, is printed upside-down, and has open ends. as it prints and functions nicest. There is a second build plate that includes a mix of arms with a rounded top, and closed ends, so you can pick the type you like best. Boost MeIf you like these o
