The holes are actually a bit more mundane than that. It's just a requirement of the printing process for venting when the model is printed and cleaned. The excess material build up and the like needs ports to get flushed through (it's a kind of printing wax used during the printing process, is it not?), so the gaps are necessary on all non-solid models.
Needless to say the model renders look bloody fantastic, Mel! I do wonder how it'll be in that grainy 'WSF' material. Hmm, guess I'll need to do some more commissions and built up some hobby funds for one. Though I still need to finish the last half of my own little SSD/Mod. Bleh.
