This is the 3D printed enclosure for my portable Raspberry Pi Pico LAN Tester.

The device uses a Raspberry Pi Pico, W5500 Ethernet controller, SSD1306 OLED display, custom PCB, LiPo battery and USB-C charging. The case includes openings for the OLED, push button, RJ45 Ethernet connector, USB-C port and side switch.
