I briefly saw some threads on here about files not being compatible with programs or something, and I use a old CAD program called pro/desktop that requires me to export the files to .step anyway so I thought I'd share what I have. Your cad programs should be able to import these no problem. I only have the andymark kit done at the moment but I'm working on the others. Heres the zip for the AM kit:

Let me know if you want more, I'm not sure if anyone will use this lol
