The file 'Fixed Hollow Parts (H7&H9) For Delta IV Heavy With Orion Exploration Flight Test 1 3D Printer Model' is (stl) file type, size is 567.0KB.
idk if its only me or not but I've noticed that the original files for the H--7 part don't have a notch to snap fit the H--5 (also the nose cone H9 doesn't snap fit into H8) below so I've managed to add the notch from the other parts and combined the files. Print this fixed version as how the original poster suggested I do not own any of the work just thought sharing this fixed file will help.
