I orderd an enclosure for the A1 mini for test.
its a foldable one.
I ask myself , do I need it really or not?
I dont see the advantage except dust cover when not printing.
I print PLA mate with closed window and that wont work lot of stringing and other strange behaviour.
If you just print PLA it’s not really needed. If you have it directly in line with an AC vent it might help as a draft shield but that’s about it. Bambu recommends against it.
I use the enclosure on my H2D and X1C for ABS, when printing PLA there isn’t a need. I use a GEKO build plates for PLA and they do not require any heating, so cool is better.
