• Source: Customizable Self-watering Insert (Printables)

Description

After printing numerous self-watering planters and inserts, I realized that the pot itself is often the most time-consuming and resource-intensive part to print. In reality, finding affordable and eco-friendly pots at local garden centers or hardware stores is incredibly easy.

While many existing inserts can work with a bit of scaling, I wanted a more precise fit. To achieve this, I developed an OpenSCAD script that can be customized to fit almost any pot size, specifically designed to accommodate pots that taper outwards towards the top.

Customizing Your Insert

This model uses OpenSCAD to generate the STL file. You can create an insert perfectly tailored to your needs by adjusting the five key variables at the top of the script:

• container_radius_top: The radius of the pot at the top (mm).
• container_radius_bottom: The radius of the pot at the bottom (mm).
• container_height: The total height of the pot (mm).
• wall_thickness: The thickness of the insert wall (mm). Note: This is measured inwards, so it will not affect the overall radius or height of the finished part.
• print_indicator: Set this to true if you wish to generate a water level indicator. (This can be separated into a different object in your slicer; it requires a float, such as styrofoam, to function.)

Tip: If your pot is a straight cylinder (not tapered), simply set the top and bottom radius to the same value.

Printing Guidelines

• Tested Settings: Printed successfully with PLA at a 0.3mm layer height and no supports.
• Water Indicator: The indicator designed for the spout must be printed upright and requires supports due to its geometry.
• Slicing Tip: If you want to print the indicator in a different color without an MMU, use the "Split to objects" function in PrusaSlicer to separate the parts.
• Note: Inserts designed for pots with a significant taper (large difference between top and bottom radius) may require supports. In these cases, the spout should still function, but the water indicator may not work as intended.

Water Indicator Assembly

To make the water indicator float, you will need to attach a small piece of packing foam or styrofoam to the bottom. I recommend using super glue or wood glue for a secure bond.
