The cheapest way to get my 3D printable model is to subscribe to my Patreon page: https://www.patreon.com/vfb_paleoart
The artist that posed these models is Medium Master.
You'll get 3 STL files for 3D printing, each with a Pachyrhinosaurus in a unique pose:
Some sanding after printing can be necessary.
YOU CANNOT SELL OR TRANSFER THE FILES OR THE PRINTS FROM THE FILE. YOU CAN PRINT THEM FOR PERSONAL USE.
