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 1 zip archive with 3 STL files:
All the pieces are keyed and presupported and scaled at 1:35.
YOU CANNOT SELL OR TRANSFER THE FILES OR THE PRINTS FROM THE FILE. YOU CAN PRINT THEM FOR PERSONAL USE.
