6" to 4" reducer with hose connector and end cap

I needed a vent reducer (6" to 4") that could be swapped between being capped off and connecting to a 4" hose.

Since I remixed a 4" hose connector model made with magnet slots, these are preserved but I have not personally installed magnets in my print as the friction fit has been sufficient.

All three models should be printable without supports in the default orientation.

Combined 6" to 4" reducer & hose connector with modifications on the connector to mitigate need for supports when printing the lip. Modified the connector to create an end cap to seal off the reducer when hose is not connected.
