I widened the phone stand to fit a phone in landscape mode (to look like a clock, in my case), and made the support solid to fit phones of different sizes. I enlarged the pen stands to fit my favorite wide-grip pen, which required fewer pen stands to still fit on the printer and print in one piece. I added drawers, and I raised the sticky pad holder and put a dip in the front for grabbing the notes. There is a large empty spot behind the phone holder which can be used to put miniatures or other gidgets.
You'll need to print the main body of the organizer in three parts to avoid supports, then glue together. Square the dividers and lid up against the back and the perpendicular wall of the scissor/highlighter/whatever cups.
