Diyas are the heart of major Indian festivals, most notably Diwali, the "Festival of Lights." Lighting rows of diyas during Diwali symbolizes the victory of Lord Rama over Ravana and the welcoming of prosperity and Godess Lakshmi (the goddess of wealth).
Tired of oily Diyas? In this tutorial, I will show you guys how I created these super simple 3D printed Diwali Diyas which are safe, non greasy, reusable, easy to make and will last forever.

Components Required
The two main components that you need for this project are:
1. 10 x Edison Candle Flames 🔗Click & Buy: https://s.click.aliexpress.com/e/_c2Qg1EBf
2. 10 x Power Jack Plug Barrel Adapters 🔗Click & Buy: https://s.click.aliexpress.com/e/_c3MV9tGz
I ordered them all from AliExpress, the links are in the description below.
3D Printing
Using Microsoft 3D builder I designed the 3D model for this project. The front features a groove to hold the flame, while the rear has a hole for the power cable.
In many Indian homes, a diya is lit at the entrance or in the home's temple every evening. This act serves as a beacon of welcome, not just for guests, but for positive energies, while keeping negativity at bay.
For 3D printing, I highly recommend using PCBWay. I have consistently used their services for my projects and can confidently endorse their quality.
The diya is important because it is a powerful symbol with four key dimensions: spiritual, philosophical, scientific, and cultural. The tradition of lighting diyas is not just symbolic; it has a sound scientific basis, often explained as an ancient wisdom for a healthy life.
The body of the diya was painted using acrylic colors, utilizing a custom blend of Raw Sienna, Burnt Umber, and Crimson to achieve an earthy brown hue.
No Hindu ritual, from a simple daily puja to a grand wedding, is considered complete without the lighting of a diya. Lighting a diya is a primary act of welcoming the divine. It is believed that the flame attracts positive, divine frequencies and deities, creating a pure and sanctified atmosphere for prayer and meditation.
Soldering
With the 3D models organized, I began the physical assembly. I first wired the LED flame by connecting a 100ohm current-limiting resistor to its positive side and soldering a cable in place. For the wick, I fashioned one from readily available cotton balls and secured it with super glue. To achieve the final, realistic look, I prepared a paste from craft resin and poured it into the diya, giving it the glossy, oily appearance of a traditional lamp.
The cotton wick (Jooti) represents the individual soul (Jivaatma), and the oil represents negative traits like desire and ego. By burning in the flame of the supreme soul (Paramatma), the wick sacrifices itself, consuming these impurities to achieve union with the divine.
Demo
So, this is how my final setup looks like.
