replacement of the ceramic nozzle in the sandgun

It's a good idea to download ceramic nozzle replacements into a sanding gun as it is in the picture, with a diameter of 4, 5, 6, 7 mm. I pushed them out of PLA plastic. It keeps a bit less than the original ceramic nozzles, but their price is incomparably lower and you do not have to buy a whole set of nozzles when it sands well with one diameter. I personally sand the best with a 5 mm nozzle..
