Low pressure garden bed irrigation V1

Garden Bed Sprinkler for low Pressure and low Water Flow

June 10th 2026: 

While this model is very popular and got lots of positive feedback, I decided to improve many details. The new parts are not compatible with this model. This encouraged me to publish it as a completely separate model. The removal of support structure is much simpler for the new model. In addition there is a new design for the part that keeps the rotating pipe in place. This will enable me to provide other pipe geometry to adapt the spray radius, if requested by users.

I also designed a second rib to the inlet to ensure the hose can not slip off.

Thanks to all of you who gave feedback and helped to improve the model!

As the title says this is for Micro-dip-Systems and not for the usual water pressure. Its specially designed to work with low water flow sources.

The pipe connecotrs fit the common micro drip systems with 4.6mm or 3/16'' pipes (such as Gardena). The slow water application ensures that the plants and soil can suck up the water and no water is wasted.

The first print profile includes a sprinkler that with the 1.5 bar covers a diameter of about 1m / 3ft.

In my system I can only feed three or four of the sprinklers with one 4.6mm line. I use 13mm hose for bigger distances and split off 4.6mm for about 3 sprinklers. To do so you can find sprinkler base with one or two connectors as well as my cross connector to reduce from 13mm to 4.6mm, which prints fast and with barely any print support. https://makerworld.com/en/models/1475323-micro-drip-x-split-reduction

How to assemble the sprinklers assembled with printed threads, glue only needed if you want to secure the top permanently.
 

• remove support material
• Place the pipe between base and top part. Screw top part on but not too tight, the pipe need to spinn free
• screw on the spike to the base.

I designed this inentionally as modular parts so that I can provide other spike designs if you don't have such lose soil as I have in my beds. I also can provide those spinning pipes in other shapes if you need them to spin faster/slower or more/less upward for different spray radius, let me know if you have issues.

I really would like to see, how those sprinkler work in your setup. Please share some pictures form your prints, that would boost my motivation to share more models.

I recommend using white PETG as this should handle direct sun beter than dark colors or PLA, but let me know if PLA worked for you :-)

The print profile uses combination of tree support and variable layer height. This reduces issues with overhangs in the pipe connectors.
