Overweight To Iron Man Armor Challenge: Building A $1,500 Suit That Doesn't Fit Me... Yet
January 19, 2026 · 1 min · 2k views
This is day one. I'm challenging myself to 3D print a full Iron Man suit, the Mark 7 by Walsh3d, and the thing most likely to stop me isn't the printer. It's me. I'm printing the armor to my goal size, not my current size. If the weight doesn't come off, I end up with a very expensive museum piece I can't put on.
Two dreams, one deadline
I've wanted to be fit since I was a kid, and I've wanted an Iron Man suit for about as long. Neither has happened, and I know myself well enough to admit neither will happen without a trap. So the trap is public: a 120-day clock, a channel full of strangers to keep me accountable, and a suit that physically won't fit a body that hasn't done the work.
So it's two projects at once: build the suit, and lose enough weight to get into it. If the suit is ready on day 120 and I'm still too big, the whole thing was a waste of plastic.
Before I start
Most of what I know about 3D printing and about making Iron Man suits comes from watching FranklyBuilt, and I owe him a proper shoutout before any of this works.
I'm not pausing anything else for this. The full-time job, the woodworking, the electronics and the learning challenges all keep going while it runs.
