@benbrown One thing I discovered about my PETG is that eventually I had to order a filament spool dryer to get it to print well, but your mileage will vary. Same goes for FLEX / TPU when I started trying it. FWIW, this is the dryer I got, because I didn't want to mess around with more DIY solutions https://www.amazon.com/dp/B09WRF4SSP?th=1
