8x8 seedling tray with water reservoir

8x8 Seed Starter Tray with Integrated Cells and Water Reservoir

This is a 3D-printed, two-part seed starting system I designed for growing seedlings efficiently and sustainably. It features an upper tray with integrated planting cells and a lower tray that serves as a water reservoir, enabling bottom-watering for healthier root development and easier maintenance.

The entire system was intentionally designed to use as little material as possible without compromising functionality or requiring any supports. The planting cells are all connected in a single piece and are printed with just one wall to reduce filament use while still maintaining structural integrity—perfect for fast, low-cost prints.

Features:

• Lightweight design with minimal material usage
• One-piece upper tray with integrated planting cells
• Single-wall cell construction for efficient printing
• Separate water reservoir tray
• Designed for passive bottom-watering
• Easy to clean, fill, and reuse
• Stackable for easy storage after use

Measurements:

• Single cell: 25 x 25 x 45 [mm]
• 8x8 cells 

Ideal for indoor gardening, starting seedlings for transplant, or just experimenting with DIY plant care!

I’d really appreciate every like and download ❤️

I’m planning to make more gardening-related designs, so feel free to follow for updates!

Have fun and thank you!
