How well will PETG hold up at 70°C?

I plan to make a spool core and filament clips out of PETG, and these items will be exposed to a filament dryer where temps can reach 70°C. I would be using PETG HF by Bambu Labs, it has a Heat Deflection Temperature of 69°C. Should I print these items out of ABS/ASA, or should I be safe to print them out of PETG without having to worry about a collapsed spool?
