I took a black gallon (?) pot/bucket (some plant we bought) and cut it down a bit with a box knife and band saw to work with fascia/grill. Should help keep it a little cleaner (and prevent the 'too smooth' airflow problem). Just drilled a hole at the end and used the same bolt/washer from pop charger to attach. For now I just zip tied it to the fascia (not shown here).
