this is a dragon's-teeth designs i found on a youtube video from knoop. https://www.youtube.com/watch?v=hM2YThrpq0U&ab_channel=Knoop This blueprint is all about that 5th design. it includes from 4 lanes down to 2 lanes if you dont have that much space. There is also seperated segments of that wall so you can peice it together however you like. hopefully this book is a blueprint that will fit all situations. it also have same blueprints but with MINES! integrated to it.
