Drip nozzle Eco-cap

This cap will fit water bottles with low plastic design. Unlike the usual caps with only one thread, this cap has four threads and a step of 8 millimeters (divided by 4).

I use drip irrigation tubing. It will fit inside the nozzle.

I added a cross on the conical part to stop debris from clogging the hole. I use it for hydroponics, the little balls of clay that i use would fit right in there.

This project was inspired by 3dponics, really cool place to start learning about hydroponics. They have a similar design but it wouldn’t fit the bottles that are most commonly available at my grocery store.

I used this library to make the threads in the cap:
