Protech Spare Vacuum Bags for 3D Filament - Pack of 6

If you own a 3D printer, it is important to keep any unused filament dry to ensure a better build quality of your prints. Many filament types are hygroscopic which means they can draw in moisture from the air. Any moisture can lead to stringing, air bubbles, poor bed adhesion, etc. This replenishment pack comes with 6 extra replacement bags in 2 different sizes: 3pcs 30x34cm, 3pcs 26x34cm. Perfect for use with the Protech Mini Vacuum Pump (TL4390) sold separately.
