The DUROZZLE ruby nozzle listing, bullet by bullet

Five bullets: compatibility with Prusa i3 MK2 to MK3S and MINI, Anycubic i3 Mega and Kobra printers and E3D V6 hotends; a copper alloy body for heat transfer, with nickel plating for a non-stick surface, added wear resistance and protection from copper oxidation; a real ruby tip for carbon fibre, glass fibre and metal-filled filaments; a cut and polished funnel-shaped interior that keeps material out of dead corners, against carbonisation and clogging; and a longer nozzle life across materials, PLA, ABS and nylon included.

DUROZZLE ruby and copper

Each material has a job in the listing. Copper alloy for heat transfer, nickel for the surface, ruby for the tip. DUROZZLE assigns them in three separate bullets.

DUROZZLE for abrasive spools

Carbon fibre, glass-filled and metal-filled filaments are the ones named. The fifth bullet adds that the same nozzle handles PLA, ABS and nylon, so it can stay fitted between spools.
