Petri dish to stage clip adaptor

These have been highly useful to connect 6-cm Petri dishes to the stage clips of a microscope to better control the movement of the dish on the microscope. Depending on your printer and the exact brand of Petri-dish, you might need to grow or shrink the "bumps" on the inside of the design. I originally designed these for one style of stage clip, but have been surprised at how generally universal the design is.
