This model is really easy to print. Great work, Tonton463!
Use raft. No supports are needed. I used 10% fill, with 3 shells. (It would probably even work with 0% fill.)
I stretched the model along the Z axis to approximate the dimensions of the original craft, and recut the nacelles to be closer to their correct proportions. Assembles without glue.
I recommend painting it before assembly, as shown here: http://thunderbirds.wikia.com/wiki/Thunderbird_3
Thunderbirds are go!
