I just published a post announcing the Github repository for my #168 project: https://glenn.pulpitrock.net/blog/posts/2022-08-19_168_engine_core/ First increment is six .STLs that model the T-12 class engine core, with one exception: the front end is about 7" longer, owing to modification of the prototype to accommodate a snowplow. The files are licensed for use under the Creative Commons CC-BY-4.0 license, which allows any use, personal or commercial, provided the attribution requirements are met. The repository is here: https://github.com/butcherg/DRG_168
