I just got an Ender-3 V3 KE and am currently keeping it in my garage until I can free-up space inside. My question is how cold is too cold for the printer to be okay if not in use and powered off?
I know that temps matter if I am using it (and for the filament in general). But the little bit of searching I have done focuses on the printers being powered on and in use.
Currently the past few days have stayed above 5c due to some very warm days. Just want to not damage anything while not being used.

Only thing I’ve ever heard of being an issue is that if it’s too cold the thermistor (I think) will throw and error and the heating bed won’t work, but nothing is broken, just might not function until in a warmer environment or using a heat gun to get the sensor above 0c or something. I don’t think you have anything to worry about for storage
Only watch out for condensation, temperature should be fine for well below 0C.
Also the act of printing in such space does not like it to be too cold. Your quality would start to fail. But I have successfully printed at 5C before and your ymnot trying to print there (yet… ) Another note is that your bed/nozzle temps are expected to be withing limits, mine can’t be below 0 to start printing.
Mine live in my garage year round, I have a space heater for print days which has worked into into the -20c, lucky of I hit 5c ambient but enclosed printer helps. Have had no issues with the setup for years, it’s super dry in the winter so never had any issue with condensation, maybe a different story if I brought it in, but still idk if I’d be worried, you could use some dielectric grease if you’re really concerned but I personally think it’s overkill.
Cold enough things get brittle, but I wouldn’t be concerned for storage.
I am in the south region of the USA, so humidity is for sure something I need to be aware of. But I can bring it inside for periods of time if it gets bad enough before I print, and my filament is staying inside anyway. My dad also made sure I know where the propane heater is located for quickly getting the ambient temps well above good ranges for prints. Just have to make sure to be super aware of making sure to keep the side door cracked while I am inside and the other safety stuff. Won’t be an issue in a few months once we finish a big sorting out and purging of other things in the room it will eventually live in. So glad I won’t have to worry about summer humidity in addition to heat.
