317/233/99 Great puzzle!

took me several tries to figure out how to drop things together, had timing belts, and way-stations, just long enough to deliver the parts when needed. I constructed first the left side of the tie fighter, then the middle then the right side. As I was finishing the 10 for the run I noticed the timing of the pieces, and figured out that with the timing it would be easier to have built the 4 grey box 3 long rods and stack them on a special middle 3 long rod, woops. 306 / 121 / 66

Not as easy as it looks. I liked it! Thanks

I liked this puzzle and like you say - not too hard - you just need to think primitive.
