Universal Pen Holder for Mendel

This is a set of files for a Universal Pen Holder made to be mounted on a Mendel Unit. As it is currently designed, you would also need a 6/32 threaded rod and at least 4 nuts of the same type. You also need 6 screws that will be threaded into the holes in the hexagon shaped parts. These screws are used to hold the pen in place, use whatever screws can screw snugly into the holes.
