Model derived from a photogrammetric scan I made on an American badger (/Taxidea taxus/) skull. The single STL with the skull and jaw should be printable, with a lot of support, but I mostly included it for presentation purposes. The separate STL files for the cranium and jaw should be much easier to print. As always I leave it up to you to optimize the files with respect to orientation, support, and subdivision.
It is likely that you will need to sand the condyle of the jaw a bit to get it to articulate with the cranium. The jaw joints of badgers are notoriously tight. On real badger skulls it is usually pretty difficult to disarticulate the jaw joint.
