What printer are you using?

If you print on a Bambu Lab, you can export *.stp

Meshing should not take that long. I suspect you have a bad object in the file that Rhino is having trouble meshing. Does anything select if you use SelBadObjects ? But the only way to really diagnose it is to post a link to the file for someone to download and check.

Wow, that’s about as much of a mess as I have ever seen…

779 block instances, 1 clipping plane, 34922 curves, 559 surfaces, 428 polysurfaces, 591 extrusions, 158 meshes, 4 SubDs, 200 hatches.

Mostly grouped, nothing joined, lots of surfaces with no thickness etc. Measures almost a million millimeters along the diagonal…

Sorry, but frankly I wouldn’t know where to start - maybe just first scale the thing down to a correct size for 3D printing, then count on hours of fixing. Maybe you could Shrinkwrap it, but…

It is recommended to quickly export STL using the following method:

  1. Run the ExtractRenderMesh in the command line, then select all the objects you want to export.
  2. Run the SelLast , then continue by running _Export and save as an .stl file
