This video is me bringing my very first “big” maker project full circle: an Iron Man gauntlet that’s actually wearable—except this time I rebuilt it in real metal using metal 3D printing. Years ago I printed a plastic version with flexible fingers, a working LED, and even a speaker for repulsor sounds. That prototype wasn’t just a prop, it was the starting point for my whole engineering journey—back when I was still learning CAD and soldering wires for the first time. To make the metal remake real, I partnered with JLC3DP and sent in my redesigned files so the parts could be printed in stainless steel. I talk through a huge lesson I’ve learned since the first build: do test prints and slice your project before committing to a full run, because fit is everything on wearable hardware. Once the parts arrived, I went to my grandparents’ place to paint everything into that reflective silver finish (primer + chrome), which was honestly special because my grandpa helped on the original hand too. I also upgraded the LED and show the simple 9V + button wiring, then designed a ring to stabilize the light and positioned the button so it triggers when I open my hand. The takeaway: metal 3D printing is insanely precise, and for me this isn’t the end of the Iron Man build—it’s the start of something bigger.
