Parametric Self-Watering Insert for Semi-Hydroponics

Convert Your Existing Pots for Semi-Hydro with a Customizable 3D-Printed Insert

Want to transition your beloved plants from soil to semi-hydroponics without the hassle of buying new pots? This parametric SCAD model allows you to create custom self-watering inserts tailored to your existing pots, making the switch to semi-hydro easy and efficient.

🌱 Fully Customizable to Fit Your Needs

This model lets you adjust:

✔️ Shape - Choose between round and rectangular insert

✔️ Watering system - Choose between semi-hydro and wicking system
✔️ Height & Width - Customize top, middle, and bottom diameters to match your pot.
✔️ Hole Placement & Size - Optimize aeration and water flow.
✔️ Wall Thickness - Choose between lightweight and ultra-sturdy designs.
✔️ Water Level Indicator - Scales proportionally to your insert’s height for clear monitoring.

✔️ Stands - Define how many stands your insert will be sitting on to ensure a secure fit.

✔️ Many More…

 

Perfect combination
This insert is designed to work optimally with the Customizable Moss Pole Generator (Honeycomb/Spiral) and the Customizable Ribbed Plant Pot for a complete matching plant setup. Together they provide support, water retention, and style in one coordinated system.

🛠️ Printing Recommendations

✅ No supports needed in most cases. However, if the middle cone (with the holes) has extreme overhangs or using the wicking system, enable support for that section.
✅ No infill required, but 15% infill works well without excessive material usage.
✅ Wall thickness: Thicker inserts are sturdier but require more material. 2mm to 3mm is a good balance.
✅ Check print preview: Ensure no parts are colliding before printing. If you encounter an issue, please report your dimensions.
✅ Careful removal: The insert is stable, but since it’s essentially a thin-walled structure, handle it gently when detaching from the build plate.

 

🖨️ Printing Instructions

1️⃣ Customize Your Model

  • Click on Customize and adjust the parameters to fit your pot.
  • Read each parameter’s description to ensure the best possible fit.

2️⃣ Download & Prepare for Printing

  • Save the file as .3mf or .stl and open it in BambuStudio and follow the Printing Recommendations written above.

3️⃣ Start Printing

  • Default settings should work well.
  • If you notice a large overhang in the middle section, enable supports—though in my experience, they haven't been necessary.
     

🔧 Assembly Instructions – No Glue Needed!

1️⃣ Prepare the Floating Base

  • Cut a 10mm x 10mm x 15mm piece of EPP or EPS (expanded polypropylene or polystyrene).
  • Insert the water level indicator into the center of the cube.

2️⃣ Set Up the Insert

  • Place the self-watering insert into your pot.

3️⃣ Assemble the Water Level Indicator

  • Insert the water level indicator (with the EPP/EPS cube) into the funnel.

4️⃣ Final Touch

  • Position the water level holder on top of the funnel – and you're good to go! ✅

Changelog:

V1.1 - 15.04.2025 - Raised max size to 350x350mm

 

V2.0 - 28.06.2025 - Added a slot for a mosspole

V2.1 - 24.11.2025 - Added the option to set a center offset for pots with convex bottom surface

 

V3.0 - 09.05.2026 - Major and minor upgrades/bugfixes

Rectangular Shape

Rectangular pots are now supported. Simply change the “pot shape” to rectangular and set your dimenstions in the newly created parameter paragraph “2B - Rectangular Pot Dimensions”
 

Wicking System

A new watering method called “wicked” has been added. It allows to create inserts for wicking where the bottom pillar is no longer present but instead you got holes for a wick. This makes it perfect for the use of soil. The options can be found in the new paragraph “4b - Wicking Settings”.

Minor upgrades and bugfixes

  • Fixed a bug where the watering funnel was overlapping the border when the bottom diameter was equal to the top diameter.
  • Made the height customizable so different ratios of bottom, mid and top cylinders can be adjusted.
  • Added the possibility to create venting holes on the top part of the insert
  • Added the possibility to only use 2 legs where the water level indicator functions as a 3rd leg
  • Made the watering funnel slightly bigger and adjustable
