Sprinkler Nozzle / Arc Disk Seal

thingiverse

This is a replacement part that I modeled for an old toro 300 series sprinkler. I wasn't sure what it was called, but turns out it's a nozzle or arc disk seal. Tested out on several 300-12-02 sprinklers and they seem to be working well! Be careful when removing from the bed as the blades are very thin and tended to break if they got stuck.
