From what we’ve heard so far, it reamins unlikely that Steamforge Games will make all STL files available for the public. At least witin the forseeable future.
Many have asked for it, and while SFG haven’t actually said “NO” most people deem it unlikely that offering STL files will be part of the business plans.
The Kick Off box, thematic terrain, and the Lamplighters Team are currently available as free STL files for download and 3D printing at home.
