This desk top swivel base holder has a sticky pad to attach the base and a sticky pad for the face that holds the phone.
Rather than stick the base to the cubby floor and leave a message on removal, I cut a piece of cardboard until it fitted snug in the cubby floor but still could slide in and out.
Then I stuck the holder off center to this.
For a quick fix I just used a marker to paint the card
Whole thing slides into cubby
You can still close the cubby door.
My OnePlus 3 fits nicely in situ for tunes and Google nav.
Now the reason for off center placement of the base is to allow easier movement of the swivel joint when charging.
This is actually an old setup I've been using for nearly 5 yrs but never got round to posting up.
(Every year or so, the sticky pad loses it's stickiness as dirt builds up. At this stage you remove it and wash the pad with soapy water and rinse, dry and put back.)
But I checked and it's still available from Amazon.
Better cosmetic results by painting the card but I couldn't be bothered
So if your phone isn't too big for your cubby, this £4 holder may be a neat solution for you
