One of the classic Thunderbirds by Gerry Anderson. Based on a model by Simon C. https://3dwarehouse.sketchup.com/model.html?id=4557e6fb3873dd55867979b8521212be.

Both hi-res and reduced-resolution "plated" versions optimized for FDM printers are included, as well as separate files for the top, bottom, and antenna groups. (You may wish to remove the antennae and add supports to make the hi-res and "smoothed" models 3D-printer ready, as I have done with the lower-res plated version.)

2015/1/18 Update: I've made the antennae thicker to make them easier to print.
