Vise Soft Jaws
thingiverse
Soft jaws for a 5" vise. They simply slide on from the side. It was designed for our Irwin vise but i think it will also fit the harbor freight vise, have not confirmed this though. print standing up, tall ways. pla is plenty strong enough. something like petg may work better because its more flexible and would grip the part in the vice better.
