MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
I'm assuming by "tank pallets" you mean the tracks and track assemblies since I didn't design those. You can find them here: https://www.thingiverse.com/thing:972768/files

You'll see a bunch of different track segment files, labeled Track_X_Y.stl. The X_Y represent the radius of the pin hole. So Track_1_5.stl has a 1.5mm radius pin hole. This is important because 3D printers print with varying levels of accuracy. You'll want to experiment to determine which size works best for your printer to ensure a nice snug (but not too snug) pin fit. Fortunately, those segments take hardly anytime at all to print, so experimenting with them does not take very long.
