What happened to Exporting rocket models? Would JNO bring it back?

There was a video about a J:NO player making a 3D printed rocket model from this simulation.
The video included this -
Player making a rocket
Player opening controls and using the execute bar
Types in and clicks something that exports the rocket model
Uses blender and 3d Prints it.
The end

The youtuber who did this was well I forgot his name but you will know if you seen it
