I'm not sure if this model (https://www.thingiverse.com/thing:1299544) needed supports or not to print, but I added in minor features to allow the beams and overhands to print without needing them from the slicer. Printed well for me at the default 1:100 scale.
Also, I added some platforms in the left and right wings that could be used for a perch or sorts for spotting or taking in the sights, although a tiny ladder might be needed...
