About this model
Etsy sells an "18-Slot Desk Organizer" and a matching 36-slot version, both built around 18mm-diameter slots -- 24 falls strictly between these two published presets, evidencing a real gap at a specific, unserved slot count for the same item diameter.
Fit notes
- 18mm slot diameter (matches the cited 18-slot/36-slot listings) plus 1mm clearance
- 70mm pocket depth to hold pens/markers stable and upright
- 4×6 layout (24 slots), between the observed 18-slot and 36-slot presets
