The spawn island on Minecraft seed 107038380838084 (from https://youtu.be/JFHGiv6qeX8 ) with a village I created on it. You don't even need support material to make it, it still looks good.
You can print all of it at once, or in three sections like there are provided
Fun facts:
1) the library and the large houses were made first to cover little ponds you can easily fall into.
2) like all naturally spawning villages, there is exactly one four way intersection with a well in it
3) Unlike naturally spawning villages, this is completely on the island, and has bridges instead of piers. Also has two smithies, and only superflat villages can have two natural smithies. The farms are also one block higher than villagers would place them, but it makes them more visible on a single-color model.
4) the small houses with roof access are strategically placed as lookouts
5) The beach houses next to the woods (on the same street as the large house and butcher's shop) were placed there as an extension to a road and bring the door count to 21, the minimum to spawn an iron golem (though you need 60 doors to breed enough villagers to spawn iron golems)
6) I made it in creative, copied the world to modify it for 3D printing and remade it in survival
7) you can walk onto a farm, on the roof of the large house, on the roof of the library and on top of the well. That opens up the possibility of parkour.
8) the roofs of the huts (flat vs dome) are also more parkour-friendly. Such as one block down has a dome roof and one block higher has a flat roof.
9) The island is shaped almost like a reverse Australia, complete with a little Tasmania and a Papa New Guinea
10) The small bridge was trickier to design with the minimum 3 block clearance for boats to pass and dismount underneath, whereas the larger bridge was not as necessary and taller. I made the latter because I can
11) In the original creative mode world, the small bridge has a flatter path, and I raised it up a block to put little lines of blocks underneath it to assists its printing without support material. The taller bridge has the lines without affecting clearance underneath enough to matter.
12) not a single tree was cut down to make way for the houses
13) many trees are reinforced. The isolated large tree attaches itself to the houses next to it, whereas some tree trunks have a plus shape.
