What is your ideal ambient humidity? (self.3dprinting)

I print in my basement and keep a dehumidifier on 35%. Right now it's down to 20% because winter. I have a dryer and will usually dry out a new roll. But many times I'm lazy and leave them on the spool and they usually print just fine.

My printer and filament live in my basement. We have a dehumidifier down there set to 55%. Some filament spools take a year plus for me to go through and I've never dried any of them. I have not noticed a meaningful change in print quality, but I also rarely go from an old to a new spool of the same material back to back.

I printed mostly PETG and ASA with some PLA thrown in.
