MJJC foam canon air valve knob

Air valve knob for MJJC foam canon. As it mentioned at valve description by MJJC, it might fit Standart, Pro and S series foam canons. I tested it only on MJJC foam canon Pro(v2).

I print it out of PETG with 2 perimeters, 100% infill and 0.2 layer. No need supports.
