I always wanted to store my filaments in a better way and sametime use the space below the desks where my printers are located. I dont have any space to mount any racks or shelfs to the wall. And I wanted to my shure that a shelf does not block my vacuum robot from roaming around. Ah yes and it should be maximum adjustable in size and levels and also be able to carry small filament rolls. 

So, here we are. 

All you need are 2 Wooden sticks in 14-15mm diameter per Level.

This prints without any supports as, man, I hate supports. :-D 

The printed parts you need to glue afterwards. Use the Connectors to have an easy matching of the parts. I then thought of glueing the wooden sticks also into the printed parts. Which will bring not the needed stability. Maybe I used the wrong glue or I did not wait long enough to dry. So I added 8 small screws through the side walls into the sticks. Perfect stability.

If you are using longer sticks (like I did -> 1m Stick) I would recommend to use the Inner Bow, too, so that the Stick would not bend through.

And finally, as I printed everything on an Elegoo Neptune 4max I made some split models if your printbed is smaller.
