Hot Tub Bubble Diffuser

thingiverse

The main jet on our hot tub, an Evolution 7 model, has been plagued by problems with its filter cycles and bubble size production. Rather than delivering a fine stream of bubbles, it's been producing huge ones slowly, creating a loud and annoying noise. I designed this insert to produce smaller bubbles, which significantly reduces the noise level during filter cycles. I will post pictures of it in place once the tub is drained.
