PROJECT OVERVIEW
Desk storage should not be one giant box. Desk Organizer is a set of trays that lock together: pens get their own depth, clips get theirs, and parts get theirs. When the desk changes, print another tray and click it on.
PROBLEM
A one-piece organizer always has one wrong compartment. It is either too empty, or the pens fall over. We wanted each tray to be replaceable without throwing the set away.
DESIGN PROCESS
- 01
Sort what is actually on the desk: long things, small things, things that roll.
- 02
Set the joint before the cavity. If the joint is wrong, a good-looking tray still will not line up.
- 03
The yellow tray is deliberate. It holds the smallest parts, and it gives the set one place for the eye to land.

PROTOTYPES
The first joint loosened after the print shrank. We added 0.3 mm to the plug and left the socket alone. The second print held.
FINAL DESIGN
The outside stays blunt, so it does not catch a wrist. The walls have a little draft, so empty trays stack without locking. The file is free because we want this on other desks first.
