Here's my best attempt at modeling the NASA Space Shuttle. The model is broken into pieces that will accommodate an overall larger model. My plan is to print this model so in the end it will be about a foot in length. I recommend printing with the hidden faces of each part on the bed. Each part needs supports in the hexagonal cutouts for the joints, and the vertical stabilizer will also probably need some support. Make sure to print the joints with the longer face on the bed to get the most strength. Enjoy!
