1.75mm Filament Filter Clamp

This is a Filament Cleaning Clamp that you clamp over the 1.75mm filament with a microfiber cloth interface material that you have to cut and provide. It cleans the filament from dust and small residues that collect on the filament from the environment before it enters the extrude. I highly recommended using a filament filter specially in dusty dirty environments.

Microfiber cloth is used because it provides lower friction and picks up dust effectively.
You do not need to use oil with this
