I have one of these kool mist spray mist nozzles I was going to try and use

I would hook it up to my air brush compresser (or shop air) and run at 5 psi.

I purchased one of those pumps but the only one I could get is massive, noisy and way too powerful. At that stage I gave up on the idea.

The blower doesn't have to be outside, it could be in the back corner where it won't get n the way of the platform.

I like that idea. You could route aquarium pump tubing down the wire track to the head and use the indicator holder
for the MK5 to hold and direct the tubing. The only drawback would be pumping outside air into the heated chamber.

Since the blower can work through a tube, why not mount it somewhere stationary inside the case and run the tube to the extruder?

I have not yet tested this, but the indication from others is that blowing air on recentlhy deposited plastic helps to maintain geometry. This is my solution to adding a blower to freshly deposited plastic, and uses a small squirrel cage format of fan. The advantage here is that is uses a flex straw that can be pointed wherever one chooses and is easily replacable if ti succumbs to ambient temperature. No tests yet, so no data. Sorry. Prints ugly due to unsupported section that extends out for straw.
