Modular desk organizer with 15 total options for modules. These include various storage options, pen and other office item storage, phone and tablet modules, and more. Download and print whichever you want to use.

There is also a standard base module (now 2 versions, a full and a minimal material version) that is completely optional - print in a different color or material as I did or not at all. The base does serve an additional purpose though, you can add magnets to each of the 4 sides to help "snap" the modules together. In addition, you can add rubber feet to either the bases or the tops to stop them sliding around. Both of these are optional and the links (affiliate) for both items are listed below:
