Printed in coPET with support from the blade side (not the best idea btw.). Part turned out well. Thread printed nicely all the way and fits great (faucet Emmevi). coPET allows very tight fastening. Used rubber gasket.
Provided 3 photos with different flows: regular (mostly used with old aerator), medium, maxi
Transparent filaments should be printed with 100% or nice infill to avoid this sloppy look.
