Review on 🖨️ Enhanced Printer Filaments: Unmatched Durability for Resistant Printing by Paul Varnado

Generates some filament drag but not enough to affect print quality. The foam inside only has a straight hole and is not split like a body, so you can't just pinch it in the middle of the print, you have to pass it through the hole in the middle of the foam when loading the filament. I only cut half of the foam so it can be attached in the center of the print. It definitely cleans the filament as it goes through, as you can hear the foam creaking as the extruder pulls the filament through. Would have given 5 stars if the foam was split like the hull.
