Description
This model is a fully parametric self-watering insert designed to convert existing plant pods into a passive irrigation system. It is intended to fit inside a wide range of decorative or functional plant containers, making it easy to upgrade standard pots into self-watering systems.
The design uses a clip-together construction, allowing the parts to be printed separately and assembled securely without glue.
Key Features
All critical dimensions can be customized to match your specific plant pot:
Total height
Upper diameter (plant zone)
Lower diameter (base interface at reservoir level)
Water reservoir height
Wick diameter
This makes the system adaptable to nearly any container geometry.
The pod uses a simple passive wicking system:
Water is stored in the lower reservoir
A wick transports moisture upward into the soil
Ensures consistent hydration without overwatering
The design is split into parts that:
Snap together securely
Require no glue in normal use
Use Case
This insert is ideal for:
Houseplants
Herb pots
Desk plants
Decorative plant containers
Reusing non-self-watering pots
Print & Assembly Notes
Ensure correct tolerances for your printer when scaling
Wick material choice will affect water flow (cotton recommended)
Designed for easy parametric adaptation before slicing in the Original CAD Model

Conclusion
This design focuses on flexibility and real-world usability. Instead of a one-size-fits-all solution, it adapts to your specific pot dimensions while keeping a simple, reliable self-watering mechanism. The clip-together system keeps assembly fast and accessible, even for first-time users.
