Classic Rodin Coil Silicone Mold for Resin – Custom Sizes

🌿 Craft your own Rodin coils with this silicone mold in the Classic geometry, designed for epoxy resin. A favourite with makers of resin coils, orgonite pieces and radionics projects.

🌀 Classic Geometry

Classic is the canonical Rodin coil channel pattern and our best seller. We also make two original designs, Single and Toroid, with a different internal channel layout.

🌟 What is a Rodin Coil?

The Rodin coil is a toroidal winding pattern based on Marko Rodin's vortex-based mathematics. Its symmetrical, repeating pattern is what makes it so popular with DIY builders, artists and experimenters.

✨ Easy-to-Use Mold

Flexible, reusable silicone that releases the cured resin cleanly, so you get sharp, precise coils cast after cast.

📄 Includes PDF Guide

Each purchase comes with a detailed PDF instruction manual to guide you step by step for optimal results.

📦 What You Get

Two silicone molds, one for each half of the coil, in the size you choose. Options marked “+ BASE” also include the base. Epoxy resin and glue are not included.

📏 How to Read the Sizes

Each size is written as D - d - R: outer diameter (mm), inner diameter (mm), number of turns.

🛠️ How to Use

1. Clean and dry both molds: moisture causes bubbles.

2. Pour the epoxy resin into each mold a little at a time, up to the rim.

3. Move the molds gently and lift out any trapped bubbles with a stick.

4. Let the resin cure, then take the two halves out and trim any imperfections.

5. Glue the two halves together with an all-purpose glue.
