Stupid question, but I'm still asking

I'd like to see a bracket that has the entire part under the potted material open to air. Then, I'd be tempted to buy.
I can do that to the one I posted earlier if you want. I'd prefer to make it re-use the original holes, but it would be easy to make a flat that has a hole in the center with a couple spacers for the airflow.

But as shown, I think the potting's gonna spooge whether it's hot or not.
