Where are the latest files for building from scratch?

Hi all, I’ve been reading these forums like crazy and have not been able to find the answer to my questions:

I would like to build an OpenPPG from scratch. I’m in a unique position as I have access through my job to some incredible HAAS machining centers and a waterjet, plus using SolidWorks has been my full-time job for 4 years.

I’m having trouble finding the latest 3D CAD files. I went to github.com/openppg/Mechanical and downloaded all the SolidWorks files, but it looks like they haven’t been touched since August 12, 2018, plus there seemed to be a lot of problems with misaligned holes and interferences, which made me think I wasn’t working from the latest files. Is there somewhere else I should be looking for those?
