This FUD only hollowed 1/537 NASA Space Shuttle Orbiter model has been successfully printed in FUD in 1/2500 scale (in pics) and has been created using NASA's own 3D animation files so is perfectly accurate, but NASA in no way endorses this product.To help reduce costs the model has been created hollow with a 3mm outer wall. To get these to print in such a small scale I have had to thicken some parts up to the minimum 0.3mm or 0.6mm wall thickness requirement for Frosted Ultra Detail such as the wings/tail and have had to make the thrusters all solid. I have otherwise left every detail on and every-one can be seen on the models (with a magnifying glass). I'm also selling a matching solid 1/537 Space Shuttle Orbiter along with 1/537 International Space Station, 1/537 Saturn 5 Rocket and 1/537 complete Shuttle in launch configuration to finish the collection I have also individually recreated all four meshes in 1/2500, 1/1400, 1/1000, 1/537 & 1/350 to match with other popular scales. If you require any other scale please send me a message. Enjoy.
