Dosing Tube Mount for Juwel Bioflow

I did not find any good solution to mount dosing tubes on my Juwel Rio 450 aquarium, so I decided to create one.

This design fits on the Juwel Bioflow filter without any modifications.

As I'm using colored TPE tubes from Red Sea with outer diameter ~5mm, this mount has 5.5mm holes.
