This 1/537 NASA ISS 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. I have left every detail on and every-one can be seen on the models (with a magnifying glass) even the viewport and robotic arm printed in 1/2500 scale as well as the soyuz capsules. The photo's don't do the level of detail justice. However, to get this 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 FUD such as the solar panels and robotic arm. I also strengthened the 4 large solar panel supports and added/hid a 6.5mm thick T-section along the main spine to give support. I'm also selling a matching solid & hollow 1/537 Space Shuttle Orbiter, solid & hollow 1/537 Saturn 5 Rocket and a solid & hollow 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.
