This vent adapter set is designed around a 135mm x 84mm oval exhaust port with an internal opening of 130mm x 79mm, adapting to a standard 3-inch round exhaust duct.
It was specifically designed and tested for the Panasonic FV-0510V51 exhaust fan, but it should also work with other oval exhaust ports that are roughly the same size.
This pack includes:
Straight oval-to-round adapter
90° side-exit adapter
90° rear-exit adapter
The adapters are designed for flexibility depending on your vent routing needs.
Included files:
STL files
STEP files for modification/remixing

Note:
Changing the diameter of the round outlet may break the 90° sweep geometry depending on how aggressively the dimensions are changed. The issue is usually easy to repair in CAD, but be aware it can happen.
