With this irrigation system you can water your home plants automatically during vacation.
- base frame
- cover cap
- adjustment screw
- airflow extension
What you need:
- empty Bottle
(- sealing material e.g. cellular rubber)
How it works:
Print the base frame, some airflow extensions and cover caps or spouts.
You can water up to three plants at the same time. If you only need this system for two plants just print one cover cap an two spouts.
Each airflow extension is about 80mm long and you can easily stick them together. It is urgently required that the upper end from the last airflow extension is above the water surface. So the number of needed extensions depends on the height of your water bottle.
You also have to print the adjustment screw. With this screw you can regulate the airflow into the bottle an therefore the water outflow from the spouts. Essential for this process is a non-deformable bottle like glas or hard plastic.
It´s possible that your screw will not seal the hole for the airflow completely (maybe because of improper printing) . So you have to glue some sealing material on the end of the screw (like i did...look at the pictures).
In the base frame is a thread which should fit to most bottles. So you can easily screw on all common bottles.
If your system is leaking between the joinings, just glue or melt the components together.
The Irrigation System will only work if everything is leakproof. But then it will work really fine.
I sliced it with cura and used the setting "Use adaptive layers". This setting used layers heights between 0.1 and 0.3mm and saved a lot of printing time but the result was a leaking irrigation system.
I fixed this issue by varnishing with clearcoat.
So don´t do this.
All parts should be printed with a layer heigth of max. 0.1mm an thick walls. Otherwise the leakproofness is not guaranteed.
Print with Raft and without other supports.
