This 3D model introduces a modular rear seat car tray designed for 3D printing. The tray can be used in two configurations:

Open X-frame mode – sized to support notebooks or devices up to 11.85″ × 8.07″ × 0.82–0.84″ (300.88 mm × 204.88 mm × 20.9–21.4 mm), providing a stable platform for mobile work or study.

Closed tray mode – the detachable top panel fits securely into the X-frame, creating a flat surface for meals, drinks, or other items.

The design includes an integrated cup holder (70 mm diameter, 18 mm depth) and a pivoting T-arm that allows the tray to fold for easy storage. All walls have a minimum thickness of 10 mm, ensuring durability and stability.

Length: 329 mm

Width: 327.5 mm

Height: 207 mm

Important Requirements:

-The largest piece is the X-frame (329 mm × 327.5 mm). This design requires a large-format 3D printer with a minimum build volume of 330 mm × 330 mm × 210 mm.

-Assembly requires 3 × M8 bolts with washers and wing nuts or knob nuts:

1 bolt for the pivot joint

2 bolts for securing the hooks to the T-arm

-This accessory is intended only for use inside a car while stationary. It must not be used while the vehicle is in motion.
