Nozzle Set for Zortrax Inventure & Zortrax M300 Dual

Since purchasing my M300 Dual almost 3 years ago, I have accumulated about 1750 hours of total print time. Over half that time was spent printing Z-glass and Z-PETG for table lamps, car door handles, and ceiling light fixtures. Both of these plastics have a tendency to clog nozzles. I try to immediately clean the nozzle each time by printing with Z-UltraT for a bit (the ABS trick). I used up 3 or 4 nozzles in 600 hours before learning that cleaning trick. So, I've gotten a bunch of print hours since then. But eventually, the nozzle will still clog, as mine recently did. So, it was great to buy some replacement nozzles to get back to printing...

Was surprised to see there were 2 in each Package at that price.
Haven't needed them yet, just security in case something happens on a weekend.
