Wall thickness seems not 1.2 - 1.4 at least with 0.4mm nozzle 50% in fill it print only outer perimeter and inner perimeter no infill between those. I'm sure cap between perimeters wasn't 0.4 - 0.8mm
Because water tightness of this model heavily depends from you slicing settings as well as you printer.
Could please you share setting what you use to print watertight.

  • layer height
  • Infill %
  • nozzle size
