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.
