Seahorse Self-Watering Mason Jar Wide Mouth Planter

Share this:

This small self-watering planter has a water channel on the side to refill the water without needing to unthread the mason jar lid for convenience. I recommend printing this seahorse tail with multicolor or color-changing filament. This fits 16 oz mason jar with wide lid.

Approximate Dimension: 3.5″ wide x 4.5″ height. The mason jar opening inside diameter should be at least 2.675″ and the depth from the top of the jar should be at least 4.6″.

For more information about planting and watering, and recommended printing settings, see our related post: Self-Watering Mermaid Tail Mason Jar Planter project.
