RE: Active chamber heating mod
So I now covered the fans with a empty parts bag I got with the printer kit. I attached it on top with two little magnets and let the bottom hang loosely over the fans. This way, the blowers can still operate and will simply blow the plastic foil aside as soon as they need to, but as long as I try to not loose warm air, the fans are closed.
I love that solution -- and in particular I love that you did not design and 3D-print some complex frame with articulated blinds. 👍
"If all you have is filament, everything looks like a 3D print" is such a common reflex in the community...
RE: Active chamber heating mod
I think it is the better solution, since you want minimal mass (in order to not block airflow / fan action). The plastic bag falls nicely into place but I think (has to be tested still) that it is also easyli blown open as soon as the fans kick in...

Like this? Core One Flaps
Reminds me of "truck nuts" 🤨
RE: Active chamber heating mod
I removed my printed flaps, i found them way to stiff(a plastic bag is probably superior in that regard), so they block to much air when ventilation really is needed, and didnt do much difference to the chamber heat. Maybe it would make a bit more difference now that my workshop is cold, but i put a blanket over the top of the printer that also covers the rear outlet instead during wintertimes 🙂
RE: Active chamber heating mod
@Cédric:
Stiffness would have been my first guess... I think to make this work, there has to be a really smootly running hinge for these flaps - or they have to be just as thin as a foil and made from a filament that allows for excellent flexibility.
I added a picture of my solution...
