Mathematically correct, this chakra means a lot for those of us who practice Sanatana Dharma, also called Hinduism. Ideally, you would keep the 54 x 54 x 27 mm size or scale to 108 x 108 x 54 mm (~200%).
It is built on the Shri Yantra, and I learned a lot while making it, for which I am grateful.
It is said that wherever a Shri Chakra resides, so does Divinity.
In honor of Shri Ganesha's birthday, I upload this in hopes that this form can be of help around the world.
(Please use white, metallic, or other light color to make the Shri Chakra.)
