A handy in-game Villager Cheat Sheet I built as a reference while working on a villager related project.
It helps to quickly find certain villagers, inspect their models, and see the NBT tags needed to summon them.
All the zombie villager variants are included as well and the custom names seen in the screenshots can be toggled on and off with command blocks.
I know it's not really a build but maybe it can help someone else as well.
Schematics for Litematica and WorldEdit are included in the world download.
