I didnt really find a desktop organizer on Thingiverse that I liked, so I built this one. It has a spot for post-it type pads, pens, pencils, scissors, business cards, or whatever you want to put wherever.
Made it with Colorfabb Marine Blue PLA/PHA at the following settings on my Ultimaker 2:
Layer thickness 200 microns
Printed at 210C with 50C buildplate coated with Elmers Jumbo Glue stick
