HPA pump coupler dust cap.

This is a simple dust cap for the quick coupler on my high pressure air pump for my air rifle. Dust in the seals of the gun could cause big problems so a cover was needed. It's a standard 1/8 HPA female coupler. You find them on paintball guns and PCP air rifle pumps.
Material is 618 Taulman nylon which allows it to stretch a bit for a snug fit. Nylon print temperature is 240C.
