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 nutts of the same type. You also need 6 screws that will be threaded into the holes in the hexegon shaped parts. These screws are used to hold the pen in place, use whatever screws can screw snugly into the holes.
