these are 2" x  3" the height under is a little over 1" these are SHORT.  a tall vehicle can go on the top level. the middle and bottom are the same specs

will add different print profiles so you can print more "Posts" as well as more of the floors in the middle of each level.  the top will be a separate print profile as well

to keep stacking just keep printing “posts” and "Middles"

***these fit loose!!** they are held together by gravity they do not click into each other.
