Air Filter - Top Cap

Hello,

This is a Air Filter I've made to replace (and enhance) a broken one i've received.
The outer diameter is 90mm.
The depth from the flange is 9mm deep.
The screw hole diameter is 6mm.
Thread is 1.5mm and Ø18mm

I wanted to upload and share a test to see what happen to my creations and to learn how to manage creation, sharing, copyright and eventually money earning.
So I took one of my most humble creation, this Air Filter.

If the experience is good I'll plan to upload much mor
