filament spool wall mount

I wanted something where I can store my 3D filament. I looked online for a design but couldn't find anything I like. So I made one myself and wanted to share it so you can build it yourself.

Mine is 110 cm wide. The wooden bar is 17 cm of the wall. The hole for the wooden bar is 22 cm in diameter. I have added multiple variations of hole size so you can pick the one you need.
