Case for CrowPanel 2.13" Epaper

Snap-Fit Case for CrowPanel ESP32 E-Paper (2.13")

A precision-engineered, two-part protective enclosure for the CrowPanel ESP32 E-Paper HMI 2.13-inch. This design features a "sandwich" structure with a dedicated main body and a secure back cover, specifically optimized for the asymmetrical bezels of the 2.13" e-Paper display.

🛠 Key Features

• Tool-less Assembly: Features integrated pins with spherical locking joints. The case snaps together firmly without the need for screws or glue.

• Precision Alignment: Includes an internal alignment step (rim) to prevent the back cover from shifting and to ensure a dust-tight fit.

• Asymmetrical Bezel: Custom window dimensions ($6.0mm$ left, $8.0mm$ right) to perfectly frame the active area of the CrowPanel screen.

• USB-C Access: Perfect cutout for easy charging and programming without removing the case.

• Compact Footprint: Minimalist wall thickness ($2.0mm$) and slim front bezel ($0.8mm$) to keep the device pocketable.

• Supports: None required. The model is designed to be printed flat on the bed.
