I've been considering getting refills to reduce my plastic consumption, which means I would have to print master spools with PLA or PETG.

Because I don't consume my filament quickly enough, I got the Sunlu S2 filament dryer, which heats up the filament to 50-60C.

My question is: would it be OK to put a master spool in the dryer, or could it potentially deform?

PETG will not, the glass transition temperature is 80-85C. For PLA it's 55-60C, so those will go floppy if you go at full tilt, though you should dry PLA at 40-50c-ish.

Got it, so I should be safe if I print it in PETG. Thanks!

Yeah, PETG or ABS/ASA would probably be my go-to. For what it's worth, I'm pretty sure basically all commercial plastic spools are injection molded out of ABS.
