Description
"Tray-Rack" Laptop Organizer
This model is designed as a modular, low-profile bracket system that mounts to the edges or the floor of a standard sliding keyboard tray.
1. Design Overview
The rack consists of two identical mirrored brackets (left and right). Instead of one large, heavy piece, this two-piece design allows you to adjust the width to accommodate anything from a 12-inch MacBookair to a 16-inch MacBook Pro.
- Capacity: 3 horizontal slots.
- Orientation: Laptops are stacked horizontally with a 1° back orientation to prevent accidental front-sliding, and fits the low clearance required for the tray to slide under the desk.
- Open top: the upper slot is open ended so when you can pull the tray and open the topmost laptop. also allows to storage thicker laptops than 20mm
- Material Recommendation: PETG or PLA
There's a second plate with a “mid-piece” if you want to have 2 sets of laptops next to each other.
3. Technical Specifications
To ensure it fits most desks, the model would follow these approximate dimensions:
| Feature | Dimension | Reason |
|---|---|---|
| Total Height | 80mm | To clear the gap between the tray and the desk underside. |
| Slot Gap | 20mm | Fits modern MacBooks and most "ultrabook" style PCs. |
| Depth | 250mm | To fit up to 16-inch MacbooK Pro |
