Description
Large volume root irrigation system, for large plants, shrubs and small trees etc.

This design is made of four parts:
- A Spike that reaches down into the ground.
- An Extension tube, for when you want to go deeper
- A Funnel that you pour water into
- A Cover plate, to stop dirt and small animals falling in.


This is for when you want to get a lot of water down into the roots. Compared to watering on the surface, this prevents wastage lost to evaporation, and from water simply running off sideways and not reaching the plant at all.
Depending on the depth needed, you may want to print one (or more) of the extension tubes.
The bottom spike has a couple of holes going out sideways near the bottom. (They are on the sides, and not on the bottom, so they don’t get plugged up with soil when you push it down into the ground)
Printing notes
This prints well without the need for supports.
You may get a small amount of stringing where the threads start. This can easily be removed. Take care not to ‘cross-thread’ the parts as you first join them together. It’s designed to be a reasonably tight fit, so you may need to work them back and forth a few times.
They can be printed fine in PLA or PETG. Some may be concerned that PLA is biodegradable and won’t last on the soil, but it will be fine (they only ‘biodegrade’ in commercial recycling devices).

PETG is more temperature resilient than PLA, so if you are using this in very hot climates you may want to use PETG. Having said that, the Coverplate is the only part that will likely suffer as it is exposed to the sun, while the rest will be kept relatively cool by the surrounding soil.
Usage
Screw the pieces together first, and then place into the ground. They are strong, but be kind and work the soil first, preparing a hole for it and then backfilling around it. It‘s not critical, but I’d aim for the top to be ½ inch / 1cm above the ground level.
The cover plate is perforated, so you should be able to water onto that and the water will go down into the funnel: no need to remove it.
