Milk is way too expensive for me to be wasting it on Filament. Milk was more expensive than gas where I lived at one point. $5.20 I think it topped out at…

Unspoiled milk is likely too expensive, yes, unless you already own the cow.

I can just picture it now…milking the cow for filament.

Or goat. You know, the genetically modified type to incorporate spider silk proteins… We live in stranger times, after all!
