Tiêu đề Yet another - Nắp lỗ thông hơi 150mm Tóm tắt Cánh đảo

Could not find something that fitted my needs. so here is Yet Another self closing vent cover for a ~150 mm pipe. Top, bottom and centre flaps are are slightly different.

print 3x center flap

I tapped the wholes in the flaps with an M3 and used 10x hex head screws (10-20 mm) for the flaps
