PE details from NewWare are also covering the holes through the thrusters for the clear part of the outer shell. I followed the NewWare instruction sheet with one exception, the white part depicted below is not covering a hole through a thruster but through a vent line. You should use part 32 instead of part 31 (don't worry NewWare provides spares) and it should be white and not red. The 2 white hemispheres provided by shapeways (see CM internal wall-cutaway version or the spare Urine dump nozzles and sea anchor attach point) are placed opposite the urine dump nozzles.
