I wonder, have any astronauts done 3D printing in Outer Space?

Yes, they have. As I recall, the first item they printed was a wrench.

Excellent! I can imagine the frustration of astronauts if they are missing a particular tool they require. (I've seen news reports of astronauts accidentally losing items during spacewalks.)

That gives me an incentive to print some wrenches. I've printed numerous objects for my hobbies and workshop. Some wrenches would be useful for my granddaughters in working on their Erector construction set builds (light-duty use, will use nylon for durability).
