I think other posters have done a good job explaining conceptually what a Tesseract it, but maybe you’re also wondering what [these well know 3D tesseract models are](https://media.printables.com/media/prints/146580/images/1383071_9e6af9d4-08d9-4d1a-a9d8-e3ef93b5b503/thumbs/inside/1280×960/jpg/88693291339c588951373115531ede4a_display_large_14.webp)?
