The file 'Ariane Class (TOS) 3D Printer Model' is (stl) file type, size is 5.7MB.
Here is my kit bash based on the Ariane class starship (https://fasaststcs.com/index.php/thefleets/united-federation-of-planets/star-fleet/ariane-class-vii-frigate/), using Captain Mojo's Star Trek FASA Federation Parts Kits.
It's scaled to 1/3900 but it should be easy enough to re-scale in the slicer of your choice.
I made it in OrcaSlicer.
