Downloaded 3D B17 model, converted to voxels using https://drububu.com/miscellaneous/voxelizer/?out=sch, exported as schematic, imported using worldedit tool, rebuilt and detailed manually. Check out the references used for detailing and inspiration.

Please don't reupload without first asking permission, feel free to reupload in custom colors of your choice. I went for a silver chrome and red color for my B-17.
