Export STL file issues (Pro Subscription, not web edition)

This old topic refers to SketchUp Pro. The problem that was reported by the OP in this thread has been fixed.

What exactly do you find difficult about getting .stl files out of SketchUp Shop? It works fine for me. I just downloaded the .stl file for this model…

…and uploaded it for 3D printing with no problems at all.

Interesting. You’re the second person in two days who says they are doing that. There shouldn’t be any need to involve MeshLab in the process.
