Filament spool holder for a door

This is a Remix of Thing 2264838 by "JDolven"

This spool holder has been modified to be attached to a door.
In my case it's a door that will normally stay open all the time.
You cannot close the door until you remove the spool holder!
So keep that in mind.

You can use the following things to build / use it:
Steel Rod 8mm x 1000mm
Nut 8mm
Janbex PLA Filament 1KG
Creality CR-10S 3D-Printer
