I have been starting to get in filaments that are more hygroscopic (absorbs moisture) than standard PLA such as PETG and TPU. My partner saw a deal on the Sovol 3D filament dryer that holds two standard size rolls and has filament holes for dispensing filament to the printer while drying.
Using it is pretty easy and the supplied instructions are good. You can set the temp and length of time you want to dry the filament. Construction seems good and works well. No complaints.
