DeskMate

Finally I broke down and made a custom thingie that fits those items that seem to live on my desktop constantly. Holds two pens, two sizes of post it notes, my two swiss army knives, my small bottle of Refesh eye drops, a few paper clips plus misc stuff such as stray batteries, etc. You probably won't require an organizer to hold these specific items but, of course, you can put anything you like that will fit into the openings. Printed fast at 10% fill, PLA.
Addendum: Updated to make it easier to get to those last few post-it notes using your thumb or finger, enlarged the smallest rectangular opening and deepened the round hole.
