Yet another filament dust filter here. The best one, if you ask me! • Simple snap-fit design • No screws or other fasteners needed, only the printed parts (and a piece of sponge) • Can be hot-mounted onto a filament without fully reloading it (i.e. you could snap it onto a filament at any place; you don't need to thread the filament's open end through it) • Fully parameterizable design with a FreeCAD source attached
