This is a remix of toniet's caja nodemcu 1.0 case.

Modifications:

• Increase the width of the NodeMCU to fit my model (CH340G ESP826 NodeMCU v9) It will -not- fit toniet's nodemcu board without decreasing the width again!
• Add a slot for housing a simple mechanical relay, i.e http://opensourcehardware.it/it/elettronica/426-1-channel-relay-module-5v-10a.html

Notes:

• Blender, STL and gcode files are included
• Rotate the top cover in your slicer, so that the ceiling is printed first
• Successfully printed using
  • ABS (240C, 110C hotbed)
  • 0 to 20% infill
  • 0.2mm
