Why a Custom Case?
When you're building a home cockpit, cable management and mounting matter. ESP32 boards sitting loose behind panels are a short circuit waiting to happen — and after the third time I knocked one off a shelf, it was time to do something about it.
The solution was simple: a purpose-built enclosure that mounts to a DIN rail or directly to a wall, keeps the board protected, and still exposes every pin.
The Case
This is a 38-pin ESP32 housing, remixed from the excellent original by sternli27 on Printables. The base design is clean, functional, and exactly the right size for the ESP32 DevKit boards used in CockpitConnect. The remix adjusts the mounting geometry and tightens up the lid tolerance for a better snap fit.
It prints without supports on most FDM printers. PLA works fine for indoor cockpit use.
Print Settings
- Layer height: 0.2mm
- Infill: 20% (gyroid or grid)
- Supports: none required
- Material: PLA or PETG
- Estimated print time: ~30 minutes (varies by printer)
Installation
The board slides in from the top and the lid snaps shut. Two M3 screws handle panel mounting. The case exposes both pin rows fully, so you can use Dupont cables or soldered wiring without removing the board.
Label each case with the controller MAC address (or name like EFIS) once mounted — it makes identifying boards in CockpitConnect much faster.
Printed Results
Here's the case fresh off the printer, no supports needed and a clean snap fit straight away.
