Drew this up quickly in Fusion360. It easily holds a Note 9 with an Otterbox Symmetry case on it while charging. There is also a 14mm x 14mm slot for an earbud, but could also be used for a pen/pencil.
It's well balanced and only took about 3 hours to print at .2mm layer height and 60mm/s speed.
I hope someone else can use this, because I really like it a lot more than I thought I would.
