Addendum to last night's post. My machine gave me a present this morning; a perfectly formed fan and housing for the AC unit. Thickening the blade's cross-section did the trick. There's round pin on the bottom. I could have had the hole made in printing, but decided, this time, I just drill it in post production. Just because I can print something doesn't mean I can't do more work on it… right? I have to drill and install the wires for the fan guard. One blade's trailing edge didn't quite form right. Don't know why that happened. Right now the machine's working on the leg assembly. I added more cross bracing to the leg frame to help resist any warpage.
