I am a high school librarian just learning to use a 3d printer. I have created a simple shape to print in Sketchup Pro 2017. I am trying to convert the sketchup file to an .stl file and have gone to export and from there to the 3d model option. When I go to save as type - .stl is not an option.
Any idea what I am doing wrong? We use an orbit inksmith and their intro video says you can only use .stl files with it.
Any help would be greatly appreciated!
PS If the issue is that I need to install an extension, I doubt I have authority to do that. I can get the IT guys to do it, if I need to.
