For Raise3D N2 / various printers with E3D / Olsson Block /Matchless Block.
These nozzles will allow you to print spool after spool of Carbon Fibre, Bronzefill and other abrasive materials. They also leave a particularly beautful print with PLA , ABS and other filaments.
Printing Carbon Fibre on a standard Core will destroy it completley in a few hours, or less than 500g filament.
This nozzle can print all day long, week after week.
Many users experience that the EVERLAST Ruby “paid itself back” after 1 time use only!
