I needed a air filter unit for a free mower that was given to me. I found a cover designed by konis1904 https://www.thingiverse.com/thing:4541094. Printed really nice. Had to design this base plate for my mower. My unit had to be printed mirrored because carburetor on other side,550EX Troy Built. Check you mower for direction TinkerCad. I added 3/4x1.5" pipe for hole to collect oil fumes.
Had problems with the pipe being to large for vent hose. made it smaller, 5/8"x3/4", 15.6mmx38mm.
