An attempt to make a Sketchup model from Stetchup Warehouse 3D printable. I think it worked :)

I attached sketchup files so you can modify as you need.

Use Thunderbird4-Exterior-whole.skp file just to see how the model looks like. If you want to modify anything use Thunderbird4-Exterior.skp file.

I had to make my own grills, they are in Thunderbird4-Exterior.skp file.

Instructions You will need 3x side-and-top-exhausts.stl 2x intake-for-motor.stl for each motor 6x intake-for-exhaust.stl two for each side of side-and-top-exhausts.stl everything else is self explanatory. Red stripes and windshield are painted with acrylic color. Look at the pics and have fun (with kids) when building and painting it.
