Here is a simple tilt adjustable method I use with success.

Needed;
Stick on Velcro
Thin plastic sheet (I used one from the cover of a notepad).
A piece of one sided tape.

Tape the plastic sheet to half of the holux, I made a small cut away section to allow more of the tape to grab the holux.

Stick on half the Velcro tape on the holux and half on the plastic.

There you have it, a nice little adjustable device.

When storing the device to avoid it constantly grabbing materials bend the Velcro onto itself.

Enjoy
