Stacking extension for Knife display stand

This extension works with my

or 4 Knife display stand (for medium to big knives)

Print 2x wall (it is ambidextrous) and 4x connecting bar, These bars have special humps that hold everything together. Watch the pictures and it will become clear how to put all parts together! :-)
