From some time ago (2018) the Printable Scenery, Country and King line of STL buildings exist. These run from castle structures to fam fields, walls, farm buildings, city/town buildings, King's Gate and Tower, etc. This is a large line of structures, scenery and some figures for printing. I found them on ETSY as printed versions from several vendors.
Look at the Country and King buildings. "Realistic 3D Printable European Buildings for Table Top games from the Middle Ages through to the 20th Century for Wargames and D&D"
This Norman Period building line had a kickstarter shown at:

Despite all logic I have obtained many of them and I feel they are very nice. I have even made modifications to a few successfully.
They are available printed on ETSY from several vendors/printers. I like Dungeon Artifacts for price, service, print quality and responsiveness.
