Early in my FichtenFoo Patreon, I released a several sets of modular shipping container buildings for cyberpunk and post-apocalyptic dioramas/scenes called District 74. This was designed for 1/35 scale to make it usable with many of my Industria Mechanika kit releases as well as existing military and civilian kits offered in the same popular scale.
The first set focused on mainly several types of container buildings, while the second focused on raised platforms and walkways to connect and elevate the modules or to be used as docks for many of our 1/35 scale airship kit releases.
The District 74 sets were available to my upper-tier FichtenFoo Patreon subscribers as part of my monthly digital-kit drops during January and February 2021. After that month, the files were added to the Industria Mechanika shop as a retail-priced digital kit product. You can purchase the digital-kit files complete with instructions and print your own District 74 sets here and here.
