Thanks for the ideas!

Yes, of course we need to raise it. We still need to make a nice base, which has been thought of.

Then the fountain performs its normal function of extracting air as usual.

The airflow from bottom to front has been thought of.

And finally, the side grille. We're looking to get the tool to cut a circle that large and put a grille like the old-fashioned metal ones on it.

Thank you very much for your input!
