Laboratory cold water Tap Diffuser

thingiverse

This is a diffuser for standard laboratory type taps where you can't easily change the nozzle. It consists of a main diffuser body, a sealing washer and a locknut to hold it all together. Ideally print the body and lock nut in a rigid, water tolerant plastic such as PETg or Nylon and the sealing washer in as flexible filament as your printer can handle since it's intended to be squashed outwards by the pressure of the locking nut.
