My dryer has a PETG profile that uses 69C, I usually dry it for 10-12 hours just to be sure.

Have you dried it?

What about PCTG? Pretty much for anything that I’d need more strength than regular PETG I could go with PETG-CF or PCTG. The only thing that can force me to use ABS/ASA is the need for (more) temperature resistance.

Often there aren’t definitive answers, and drying never hurts;)

Have you tried drying it? Sometimes filament is not dried out of the box.

That’s pretty hot for PLA

Some of the newer iPhones feature a LIDAR scanner and there are store apps that can use it to scan too
