Calling all Marvel fans and 3D printing enthusiasts! This is a highly detailed 1:1 scale replica of Tony Stark’s iconic MK-II Arc Reactor from the Iron Man movies – carefully designed with functionality, ease of printing, and an epic final look in mind.

This project is composed of 50+ individual parts, no glue required, and fully assembled using M2 screws. It's been engineered with precise tolerances so everything fits together seamlessly right off the printer.

🔧 Key Features:

✅ No glue required – Everything is assembled with M2 screws, making it solid, easy to disassemble, and clean to build.

🎨 Single-color printer friendly – Each part is split by color in the STL files, so you can print everything separately and still get an awesome multi-color final result with any regular printer.

💡 LED-ready design – The Arc Reactor is hollowed and designed to include internal lighting. I’ve added the Amazon link to the same lights I used.

🧩 Designed for perfect fit – Tolerances are already applied for smooth assembly.

🎥 Full build video available on YouTube – I’ve documented the full process, from modeling to assembly, in case you need help or want to see how everything comes together.
