Parametric Snap-Apart Seed Trays (F3D + Open Source)

🌱 Parametric Snap-Apart Seed Trays (F3D + Open Source)

Fully parametric seed trays designed specifically for 3D printing — clean, functional, and customizable.

These trays print without supports* and feature perforated side walls so you can keep the tray as a single unit or easily snap apart individual cells when transplanting.

🔧 Features

• ✅ Fully Parametric (Fusion 360 F3D included)

• ✅ Adjustable cell count (rows & columns)

• ✅ Adjustable cell size / depth

• ✅ Optional integrated labels

• ✅ Designed for support-free printing

• ✅ Snap-apart perforated sides

• ✅ Strong enough to stay together during handling, but easy to separate when needed

Perfect for starting tomatoes, herbs, peppers, or any seedlings. The perforated edges let you break off individual pods at transplant time without disturbing neighboring roots.

*this was really non-trivial to do. They have a flat bottom but the insides are tapered so that supports aren't needed.

🛠 Customization

The included Fusion 360 file allows you to:

• Change overall dimensions

• Modify number of cells

• Resize individual cell geometry

• Add or edit text labels directly on the tray

If you don't want to install Fusion 360,  you can customize directly in Makerworld
