I needed a case to use my XIAO ESP32 as a ESPHome Bluetooth proxy. You will need a
2"/5cm UFL to SMA cable and an antenna.

Make sure that supports are completely removed around the seals - some bits tend
to stick which will prevent the case from snapping together.

Printing

  • Print standing upright on the antenna port
  • Supports enabled
  • 0.16mm layer height
  • 5 walls
  • Outer-inner wall order

Assembly

  1. Place the PCB bottom side down into the half with the tabs on top
  2. Place the SMA connector nut into the nut trap
  3. Insert the tabs into the holes on the top part of the case and snap it together at the antenna port
  4. Tighten the nut
