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.
Maybe from ALDI but certainly not a ninja brand. Food dehydrator might be cheaper, especially from some place like ALDI.
I have one of those round dehydrators I bought and modified for exclusive filament use… it takes up more space than purpose-made dryers, but it’s also quite powerful, only my Sunlu S4 can rival it.
