This 3D printed corm cup holder is designed to perfectly fit our self-watering corm cups, keeping them secure and upright during propagation.
 
The holder helps prevent accidental tipping, spills, and shifting—especially on shelving, grow racks, or heat mats. Its open-bottom design allows the corm cup to rest directly on a heat mat, ensuring proper warmth transfer without blocking airflow or moisture movement.
 
Lightweight, reusable, and easy to clean, this holder adds an extra layer of stability for growers who want a safer, more controlled propagation setup.
