Nitrox Stick Mixer_2" PVC
thingiverse
Nitrox stick mixing insert. There are 2 files, they'll change the way the air spirals through to mix things up. I have this in a 2" PVC 24" long with a Solberg filter on top. Works great, very inexpensive solution, even cheaper than whiffle balls. I printed either 3 or 4 to fit in a 24" section. Here is the plug to go with the PVC "T" at the base of the stick; https://www.thingiverse.com/thing:5319782 I did not design this, all credit to "James79" on Scubaboard. He gave me permission to share.
