My faucet Aerator was clogged when i moved in . I just avoided that bathroom. Taking the aerator out would result in my pants getting sprayed. So I designed a 3d printable aerator that fits the faucet and draws air in around the edges to increase spray pressure but reduce water flow. It works great but I had to clean up the part with a 1mm drill bit I got from a specialty store because it's proven tricky to get small features inside to print cleanly. The water jets spray into an internal chamber, where air gets drafted in and both air and water merge together through larger venturii before exiting the faucet head.
