Propagation Pod

Propagation Pod – Free STL

This is a snap-together air-layering pod designed for propagating tomato plants (and similar soft-stem plants) directly on the vine.

The pod clamps around an existing stem, allowing you to pack moist soil, coco coir, or sphagnum moss around the node. Roots form inside the pod while the plant is still attached and actively growing. Once rooted, the new plant can be cut free and transplanted with an established root ball.

Features

Two-piece clamshell design for easy installation and removal

Internal cavity sized to encourage dense root growth

Stem cutouts to avoid crushing or damaging the vine

Reusable and lightweight

No tools required once printed

How to Use

Lightly wound or scrape the stem at a node (optional but recommended)

Pack the pod with damp growing medium

Snap it around the stem and secure

Keep the medium moist

After roots form, cut below the pod and transplant
