Goodbye Invitrogen ripoff product

With the help of Ken Meacham of the Bandi Unit, we have successfully used some magnets to inexpensively 3D print our own magnetic stands based on this design and some inexpensive magnets. They look like cheap imitations, but just as well, if not better, and cost orders of magnitude less (last I checked the commercial stand in the background would set you back a cool US$531).
