Air tool dust cap

Here in Queensland, Australia we have wasps that like building nests in the air inlet of air tools. I would imagine we are not the only place in the world with this problem.

This is a new improved version of my previous air tool cover, https://www.thingiverse.com/thing:1304275
which is easier to print and fits better.
This is for Nitto fittings only as they are the most popular here.
I have not done a Ryco version but if there is enough interest, I will.

It must be printed with flexible filament. I like TPU but I am sure any flexible filament will work.
