I took one look at the concept art and said to myself there is no way you can make a faithful replica of that prop and you only get wound up trying... so I didn't.
This is my homage to the original prop made out of an old Star Wars toy, my usual simple Blue Peter/Art Attack methods.
RE enquiries as to me making one for you, yes you, right there, not you, the one behind you (some of you looked)... I made this one as a simple version that people could replicate regardless of skill level, the first one I did I cannot replicate, I used up what bits I had doing the first one plus it was a pain in the arse (ass if you're in the US). I make things because I want them and there aren't commertially available replicas not because I take any enjoyment from the making process so I don't do commissions but am happy to provide "instructions".
