Hello sports fans. Today I’m installing the Olsson Ruby nozzle onto my Original Prusa i3 MK3. In order to print more exotic filament (i.e. NylonX or Bronzefill) which are abrasive to a standard brass nozzle you need a hardened nozzle. You could use a hardened steel nozzle but I choose the Olsson Ruby instead. So watch while I install my new toy, I mean precision part, on my MK3.
If you don’t have a micro torque wrench and don’t wish to use a nut driver as I did you can print a torque tool for the Olsson. Link below.
