This is the forearm section from the Iron Man Mk42/43 armor (Iron Man 3, Avengers: Age of Ultron).

Unlike most 3D models available online, this piece was professionally modeled in full parametric CAD (Onshape) — not just sculpted for 3D printing.That means it’s dimensionally accurate, fully editable, and can be easily modified, scaled, or integrated into your own mechanical or cosplay projects.

Available in STEP and STL formats for maximum compatibility.

To my knowledge, this is the only Iron Man forearm model available in true CAD quality.I’m currently developing the entire Mk42/43 suit including the exoskeleton (with motorised parts) in CAD, so stay tuned for upcoming releases.
