Use strong double sided adhesive tape to mount the clip at the bottom side of your kitchen cabinet (I used "Pattex kleben statt bohren").

In the Clip you have five slots. Two of them are made to slip the Deuter/Source Bladders in. They are a little bit wider than the other three. Into the tighter slots you can attach thin food storage bags to dry them.

At the outer sides of the clip there are two wide channels where you can clip in the hose of the Deuter/Source streamers.

The Fusion 360 file is modular, so you can create your own combination of wide/tight and channel slots.

To widen the bladders while drying you can use my other thing: https://www.thingiverse.com/thing:6125758
