The file 'Syringe Nozzle 4.5mm Tip Flux Paste Dispenser 3D Printer Model' is (stl) file type, size is 40.0KB.
I can't find those fancy nozzles locally, so I did my own.
It's for 4.5mm tip syringe
Now the flux paste slides good. (better than using needles)
Used a brim to get better adhesion and 0.15 LH
