Has anyone tried this on the latest model A1's? I can't get air to pass from one side to the other. Seems like maybe they have a barrier or baffle between the two sides.

So here is my version…printed in pla+ with 15% infill for testing. I’m using a Ender 3 enclosure and a 120mm squirrel cage fan with variable speed controller.

Preliminary testing reveals quite a bit of back pressure and the fan has a difficult time pushing air through the entire system. I’m not feeling any flow out of the exhaust..however I believe at least “some” air is getting through as I’m recording about a 10-15 degree drop in temperature at the exhaust port with the fan running.

The case around the main board on the intake side is physically cool to the touch, while printing with the fan running, so I am confident it is cooling as intended, which to me is the main goal here.

I am open to feedback, thank you for the model!!

Minor changes. Made the top surface flush to the handle top, made it symmetrical (my brain is like that...) and filleted around the top.
Also put in dished finger-grips on the ends.
