Tried printing out the door hardware using my son's 3-D printer. Unfortunately, they didn't come out. Too small for his printer, I guess. The lunchbox came out ok.
I remember building that one, too. Sailed it around in the pool. It was pretty fast if I remember right. The kit gets bashed pretty hard by "hard-core" ship builders for inaccuracies, though.
Very nice. I like the cooler, too. I think those are pretty generic & would work in all sorts of AMT trucks. My son has a 3D printer, but I have no idea what type of files it uses.
