Robert Downey Jr. Meets ‘Most Dapper 7-Year-Old’ Ever, Presents Him With Life-Changing Gift

A video published online Thursday shows actor Robert Downey Jr. presenting a child with a gift he's sure never to forget.

"Had the absolute privilege of presenting a brand spanking new 3D-printed bionic Iron Man arm to Alex, the most dapper 7-year-old I’ve ever met," the "Iron Man" star wrote on Facebook.

Video of the exchange shows Alex Pring, who was born with a partially developed right arm, walk into a room to meet Downey Jr.

"Hey Alex, how are you? I have another bionics expert on hand so I thought I'd drop by," the actor said. "Nice bow tie by the way."

Downey Jr. then opened two large metal cases featuring bionic arms resembling those seen in the "Iron Man" movies.

"Each one looks the same," Pring said.

"Actually, I think yours might be better than mine," Downey Jr. replied. "What do you say we both try them on, do a progress report?"

As it turned out, Downey Jr.'s arm had a "technical glitch" while Pring's worked flawlessly.

The two shared a iron fist bump before the actor thanked mechanical engineer Albert Manero for building the bionic limb.

Manero founded the volunteer group Limitless Solutions — an organization that creates 3D-printed bionic limbs for individuals and makes the designs free for others to use. The technology has allowed Manero to dramatically cut costs. Pring's bionic arm, for instance, only used $300 in materials.

The group was featured in Microsoft's The Collective Project which highlights the work students are doing to improve the world.
