I haven't changed much on the model. I added a few printable ventilation grilles and installed a few cheaper and simpler parts. I shortened part of the flat bracket to make room for the PVM controller and simply attached it with superglue
I use simple USB-C fan controllers, some of which are available for as little as 8 euros. I also use slightly cheaper filters.
In the end, my configuration only cost about 66 euros + some filament.
(In the picture you can see that I didn't install any flat brakets on the sides because I only realized after printing that I had the wrong screws and could only tighten them when nothing was in the way)
