Modular Desk Organizer Post-it (3D Printable)

A fully modular desk organizer system designed to be compact, customizable, and easy to expand. The goal is simple: create a flexible workspace tool where anyone can design and add their own modules. Included Modules The system currently includes three functional modules, all compatible with the same rear connector: Post-it Note Module (76×76 mm) — the fixed reference module of the system Smartphone Stand Module — angled at 70°, stable and universal Dual Tray Module — ideal for clips, pins, screws, and small items Pen Holder Module — 5 holes (12 mm) for pens, pencils, markers The Post-it module is the core element of the system and remains the fixed reference point for alignment and proportions. Modular Attachment System All modules use the same standardized connector, allowing you to rearrange or replace them freely. The download includes a dedicated file with the exact connector measurements , so you can design your own compatible modules. Create Your Own Modules This project is intentionally open and expandable. You are encouraged to design and publish new modules that fit the system. Ideas for new modules: USB / microSD holder Cutter or utility knife holder Business card stand Rubber band or tape holder Magnetic clip tray Mini drawer Cable management module Let your creativity shape the next evolution of this organizer.
