I like the modular Hex-Shelf by JohnOldman, but i wanted to make it easier to use. I don't wanted to print all out of PETG. I wanted to combine it with wood. So i searched for some wooden plates on Amazon and changed some things on the hex adapter.

You can screw the Adapter on your wall or just use it for a standing shelf.

Insert the Plates to the Adapter and press the cap on it to fix the plates.

I also attached a little help for the first hex system, to bring it easier to your wall.

Needed dimensions of the wooden Plates: 4,5-4,6mm thickness, ~76mm depth and width

*UPDATE 25.1.2021: Updated the Template to less Material Design. Also added a Template for easier adding new HEX Cubes.

*TO MAKE SURE: You can add smaller Plates then 76x76mm, but you should aways have the depth of ~76mm and just change the width to make it fit perfect.
