Product Details

Print the mold. Wind the spiral. Deploy it in your garden. Repeat as many times as you want.

What You’re Getting

This is a digital download — you receive STL files sized and proportioned for the Ighina conical spiral form. Print them on any FDM printer (PETG recommended for outdoor durability), then use the printed mold to wind copper wire into consistent, correctly-proportioned spiral antennas.

One purchase, unlimited prints, unlimited spirals.

Who Was Ighina?

Pier Luigi Ighina (1908–2004) was an Italian independent researcher who claimed to have worked alongside Guglielmo Marconi. His agricultural and therapeutic devices centered on vortex and spiral geometries he believed could interact with subtle electromagnetic fields in living systems. His spiral antenna forms — wound in specific conical proportions — have become a staple of the DIY electroculture community.

Whether you’re drawn to the subtle-energy framing or simply interested in spiral geometries as passive antenna forms, these molds let you reproduce the designs with precision and consistency.

Printing Notes

• Material: PETG is ideal for outdoor molds (UV and moisture resistant). PLA works fine for indoor use.
• Infill: 20–30% is sufficient — the mold only needs to hold wire tension
• Supports: Minimal; the cone geometry self-supports on most slicers
• Scale: Print at 100% for the standard size; scale up for larger spirals

Winding Guide

A PDF winding guide is included with your download. It covers:

• Wire gauge recommendations for different use cases
• Winding direction and tension
• Grounding options (earth stake vs. floating)
• Placement in soil, pots, and raised beds

Personal License

This purchase covers personal and home garden use — print and use as many as you want for yourself. If you want to sell printed molds, please contact us for commercial license pricing.

Works beautifully combined with Giza Pyramid Connectors — a copper spiral inside the pyramid is one of the most popular layered passive setups in the community.
