The cheapest way to get my 3D printable models is to subscribe to my Patreon page: https://www.patreon.com/vfb_paleoart
You'll get 8 STL files:
TAIL (variant without quills)
All pieces are keyed.
YOU CANNOT SELL OR TRANSFER THE FILES OR THE PRINTS FROM THE FILE. YOU CAN PRINT THEM FOR PERSONAL USE.
