Have fun with this guys. Making an army of 1990 Ninja Turtles foot clan. Here is the model that I made of the arm/ hand guards that they wore. It is sized off of a supposed screen cast piece (unverified). This is modeled to be printed flat and then for you to heat bend the print over a round object to the desired curvature. No support material needed, but you may need to cut it to fit your bed.
