SSH1106 OLED Display enclosure (STM32 + W5500)

thingiverse

I've constructed an enclosure for my electric boat's electronics. It features a housing unit to display the battery pack's state of charge. A STM32 microcontroller utilizes ethernet to communicate with a battery management system via Modbus protocol. Navigation through menus is handled by a rotary encoder. The front panel can accommodate a SSH1106 OLED display, which I've fitted snugly into the main box. You can insert a STM32F103C8T6 and a W5510 ethernet module into the main compartment. The lid has an opening for the Ethernet port and the programming pins of the bluepill. This enclosure was built quickly, so double-check the measurements before printing. I've also noticed that SSH1106 modules come in varying sizes. Openscad files are provided for your reference. Update 19-05-2020: A knob has been added to this design.
