Seen that there is not a proper sphinx model on thingiverse I found this on the web free3d.com from the user printable_models. It has a Personal Use Only license so that applies to this model as well as it is the same. Please attribute this model to the original designer as this is only a recommendation to a nice model.
Here is the web direction to this object:
