3d printer nozzle. It is M6 threaded??. I have said it before, the mist system works best with 0.6mm- 0.8mm nozzle.

Chas, i believe you have seen the video where i go into the details?? last news is that kerosene works fine for all and will not hack the transparent vessel/ if you buy a brand one/.

At the end of the day i used 1mm tube that i pushed and orifice closed, then re drilled to size at the exit only. The other trick is the hole to be 0.8mm but the exit to be cut flat and slightly chamfered at the outer side but not the hole. If that makes sense. That produces the nicest spray pattern
