This is a replacement prop rod clip for a BakFlip F1 Tonneau bed cover mounted on a 2011 Ford F-150. The original prop rod clip broke, and I couldn't locate an exact replacement, and wasnt sure if the new versions were compatible, so I designed my own. It is designed to retain the prop rod with mild retention, to prevent unwanted movement of the rod during stowage. I recommend printing out of PETG for its slight flexibility, and temperature and chemical resistance properties.
