Medium Seed Tray with Self-Watering Base

This 3D-printable medium seed tray is a must-have for gardeners looking for a low-maintenance, efficient way to start their seedlings. Designed with 25 individual cells, each measuring 34mm x 34mm x 47mm, it provides ample space for growing a variety of plants whether herbs, flowers, or hardy vegetables all in one compact unit. The deep cells promote strong root development, while the innovative fold-open design allows each cell to split apart effortlessly, making transplanting stress-free and preserving delicate roots.

What sets this tray apart is its built-in self-watering base. The lower tray collects excess water and wicks it back up to the cells, ensuring consistent moisture levels without the need for constant hand-watering. Tiny drainage holes in each cell prevent over-saturation, creating the ideal environment for healthy plant growth. This feature is perfect for busy gardeners or anyone looking to simplify their seed-starting process.

Assembly Notes

• Fold all four sides of each cell inward on itself before placing into the tray
• The cells will flex into shape don’t force them
• Warm plastic folds better
  • If the print is fresh off the bed, it’s ideal
  • If it’s been sitting in a cold shop, warm it slightly before folding
• Cold prints are more brittle and can snap during folding
• Take your time here once they’re in, they stay solid.

• The large print profile consists of 25 individual cells, with the base’s overall dimensions—including the lid—measuring 224mm x 239mm x 49mm. 
• The A1 mini print profile consists of 9 individual cells, with the base’s overall dimensions—including the lid—measuring 139mm x 149mm x 49mm. 
• 136mmx215mmx84mm
