Teasing aside, this works surprisingly well. The default settings for dehydrate is 150°F, which is well under the glass transition temperature for PETG.
Would not recommend for ABS/ASA. I have no idea what temperature that plastic starts putting out its toxic fumes at, and I don’t want to find out.

Ahh yes there isn’t enough plastic in my food yet, let’s see if we can add a bit more
150F is pretty much the target for PETG in most dryers as well. 60C which is 140F.
The real question is, what is that spool made from? Can it take the temperature? Do you want that leaching chemicals into your convection oven?
Maybe get a cheap one just for industrial use. Like the reflow toaster oven.
Is an air fryer cheaper than a filament dryer?
Probably not, but the goal is the convenience of multi-purpose. I can dry a filament for an hour, then wipe down the inside, load the dried filament, and cook dinner while I print.
Also banking on the air fryers capacity to blow larger volumes of hot air at the target temp, given that… Well, it’s designed to mainly cook food. Some of the cheaper filament dryers just do not have enough airflow. Or any airflow.
My questions was referencing this:
Do you want that leaching chemicals into your convection oven?
In which case, you really don’t want it to be multi-purpose.
I have heard about the pet peeve about “single purpose” devices, especially with kitchen appliances. But once you start putting non-food things in your for-food devices, maybe rethink your multi-purpose approach.
You wouldn’t use your table saw to slice bread either.
