I was annoyed that there was no way to attach the angel on top of the Zou3D nativity scene so I designed a press-fit stand that includes a platform for the angel. I included models that should fit the following sizes of the nativity: 100%, 90%, 80%, 70%, 60%, 50%, and 40%. The file is easy to size as needed. Just measure the width of vertical support beam on the stable and size the interior width of the stand to that width +0.3 mm for tolerance. You may need to adjust the y-length a little bit which is easy to do by putting the nativity and the stand on the same plate and making sure there is a little gap between the part of the stand that rests on the roof and the base of stand that rests on crossbeams of the stable.
