Star Wars Thread and Measurement reference


Master Member
So, I thought it might be useful to post a thread like this, maybe have it stickied eventually. Especially for me, I keep running back to the RPF to check measurements of vintage proprietary parts or the actual props themselves. Maybe there are some we don't know and can find...

I think it was M6 ... don't have it around me to measure, but I used a metric set screw in my build for sure and it didn't feel like I'm forcing a different thread
