I’ve been working on a 3D printable Green Lantern ring prop, and this thing is wild — it has a strong pulsating green light that honestly makes it look alive.

Minimal electronics

No solderingNo visible componentsSuper easy to useIt’s designed to be fun to build and even more fun to play with. Just pop it together and you're good to go — whether for cosplay, display, or just to feel like you’ve got the willpower of a Lantern
