Is the Polymaker PETG Refill 1.75mm worth it for high-speed functional parts?
I recently upgraded my FDM printer to a high-speed setup and need durable filament for brackets and enclosures. Does this refill hold up well under rapid extrusion without clogging or stringing?

I run the black and electric blue refills regularly on my high-flow setup. Layer adhesion remains rock solid even above 300mm/s, and skipping the plastic spool saves plenty of shelf space.
