These are the most versatile jaws you can print, they collapse past each other so they can hold a variety of cylindrical objects from a tiny wire to a large 1" diameter motor. They will also hold a PCB. This part is a pair of vise jaws.
###NOTE###
I have not tried printing these in interlocked configuration. It is more space efficient, thus cheaper to print this way. In theory the parts will separate fine but it is not tested.
