I already updated my 3D Printer fan shroud a couple of months ago. It should cool the filament more effectively and evenly. I think it did a good job. Unfortunately, the shroud got too hot several times and was deformed. I was afraid that it now had reduced cooling performance. I found an update to the fan shroud that looked very efficient, and somebody analyzed the airflow, and it appeared to be very effective in cooling the filament.

One would guess that I should have known better with the work experience I accumulated in the software engineering field.

I have an AxiDraw V3/A3 Penplotter that I bought to satisfy a desire to own such a fantastic machine. It started in my teen years working with HP Plotters in our university lab at the TUHH. I could not afford an HP Plotter back in the day, so that desire was never satisfied.
