Depends on where you live. I live in a desert where the humidity is often <10% and have left PETG and PLA rolls out for several weeks at a time with no issues. With nylons I've been a bit more careful, though I'm not sure I need to be.
+1 for Voron. I just finished up mine and am pleased with the results. Totally open source, modifiable, and unlike Prusa machines not based on a 5-year old design. (This is coming from somebody who loves the MK3S+ but was very disappointed with the MK4's marginal improvement and botch-job of a lunch)
That is an incredibly overgeneralized view of the situation. It's precisely this kind of polarization, and viewing everything in terms of black and white, that Putin and allies are reveling in.
That's a great idea. See if you can interact with it at all. Printrun is another option if you don't want to set up Octoprint.
