The clip was designed to hold a ribbon cable to a metal frame.
After building an enclosure for my Prusa I3 Mk3, I moved the control panel to the top crossbar. I designed a hinged bracket for the panel and use these clips to hold the ribbon cable in place on the back side of the metal frame.
The model was designed for printing in either PLA or PETG.
