3DP Quad Venturi

I'm using this for a 3dponics garden. My air pump is pretty powerful; even with two venturis it was overpowering them and causing air bubbles to overflow. However, I discovered that it powers 4 venturis really well.

Previously I had been printing 4 individual objects and hot-gluing them together. This is my attempt at combining 4 3dponics venturis into a single block for easier handling.
