Bathroom Bottle Holder

The toilet in the unit that I'm staying now come with this hand rail for the old and disabled, but I guess I'm not going to use it and I can't remove it. So I made a holder support that can clip onto the hand rail. I was trying out with flex material and somehow the first copy printed seems to be too soft to clip onto the rail. I changed the design by adding hooks for cable tie as you can see the photos. Finally, I cut out the holder base from plastic sheet and place on on the support.
