All ages, 6+, 10+, 13+, 17+, 18/adults only. 6 10 13 and 17 -- e, e10, t, and m, are the commonly used ones. 18 basically represents a soft ban on the game, since retailers will not stock AO games.
I totally just noticed that the circuit board one was named as challenge 17 also, I've updated it to 18. Sorry for those who posted their work already and may have used number 17. I'll be sure to double check next time.
"It's not a gun, it's a blaster." - Han Solo ( no, he never said that ). I think you should do the whole thing ( it's a DH-17 blaster pistol according to wikia, LM-17 doesn't seem to exist ) instead of just a part of it. Would look better.
Not sure if this was a max/Maya only thing, But it looked fun so i took a shot. Started simple, Then turned into this :) Also not sure if i strayed to far from the original idea. It has six "Dips" or "holes" in it. Has six of those little boxes. and the other stuff is extra, I suppose. All one piece of geometry, Could zoom…
