I'm interested in getting some air circulation in my coolidor, and was looking around for some options.

I came across this:

However, I thought to myself, why spend $70 on something that looks like $3 worth of material.

Does anyone have experience making something like this?

If so, what are the components I need?

Thanks in advance.

P.S. Humidity rises, so pushing it down is something to consider.
