My neighbor's compressor's air filter broke off - he tried to glue it back on, but the plastic does not glue up easily. So I made a new part. Or rather two.

The compressor in question is am AeroTec Aero 220/24, but I believe many other models use a similar or even the same design. 

This model consists of two pieces to aid in printing it without supports and to easily replace just one part, should it break again.

base.stl replaces the original back half of the filter, the original front half still fits on top. connector.stl is the part that screws into the pump. It has a 16mm thread for my neighbor's compressor. A M6 bolt is needed to connect the front half of the filter.

Print it in PETG with 0.2mm layer height. No supports needed.

You can modify the model as needed via TinkerCad: https://www.tinkercad.com/things/gl9PoUW16aX-compressor-air-filter
