If you have no 3D printer, .stl files are viewable in the Mac OS Finder. Just download the file, select it and hit the spacebar: a 3D rendering of the .stl can be rotated.
As the other comment suggests, any printer will do. For this particular model, I think a 3D printer with "good resolution" will give the best results. So a resin printer will probably give a smoother finished model than a filament printer.
Loaded up the models into my slicer, looks like a pretty straightforward print. Should print on anything "mainstream", I reckon. About 4h worth of printing on my Bambu P1S.
