A filament dust and lubrication filter that bolts to a 2020 extrusion rail with two M5 T-nuts (5.5 mm holes, 16 mm apart in one slot) and hangs a 20 mm sponge chamber clear of the rail. Filament drops in through a chamfered funnel mouth, passes a cut sponge cube resting on the internal ledge, and exits a 4.3 mm bore that accepts 4 mm OD PTFE tube. Overall 75 x 26 x 34 mm, gusseted so the tower does not snap off the mounting plate.
A 60 mm one-piece carabiner whose gate is a built-in flexing spring arm — press it inward to hook on, and a capture nose stops it opening under load. Prints flat with no supports, no assembly, and no metal spring; sized for keys, water bottles, and bag straps.
