Retrofit window opening bracket for old Navy facility

The windows at the facility where I work have a long boom attached to a crank that is used to open and close them. The boom attaches to a pivot fitting which is a wide metal tongue with two additional metal tabs. Most of the little metal tabs have gone missing.

I was asked to try to replace the little metal tabs, but they are too thin to 3D print effectively. Instead I developed a single large plastic part that fits over the wide metal tongue. I printed this in colorfabb nGen using 4 shells,
