A fairly exact copy of the hop-up arm used in the original Specna Arms Edge SA-E17, but most likely the same one is used in any Specna replica with a rotary hopup chamber.

There are two versions: the copy of the original part, and a sewed-off version for R-hop and similar.

Use a 2.0 drill bit to clear the hole and optionally some sand-paper to give a final touch.

Print in ABS. Donot use PET or PET-G because it bends, and also avoid PLA since it will melt on the first hot day.
