Wearable Arc Reactor

This 3D-printed wearable arc reactor is all about keeping things simple. By using an existing LED, I designed the reactor to work seamlessly without complicated electronics. While you can print everything in PLA, I chose TPU and PETG for some parts to make it more comfortable and durable. This means it’s not just a cool accessory for cosplay; it’s also built to last, making it perfect for any costume adventure!
