This description is a work in progress.
All of the .stl and .3mf files are here. I have printed them all (in PET-G) and they all work to my satisfaction.
With Sukkot only 1 month away, I didn't want to wait until I have time to polish the text and add the photos and video (I hope to get to that over the weekend).
Please send me a message if you have questions.
Gut shabbes and shana tova.
