Controller/Headphone Holder

Changes:

- Rib to support the controller weight
- Cut a part of the phoneholder part section, for I could print it sideways*
- Added a reinforcement where the section that connects with the shelf joins the controller holder (maybe I over did it, but it is holding expensive stuff)


Thanks and credits to the original designers, but there is a bread crumb trail to follow.




*The line touching the build plate was too thin, and my slider went nuts. It is still not 100%, but I could print it with no problems.
