Everyone's favorite cartoon alien as a detailed action figure.
If you should never heard of Invader Zim: In this way to early canceled TV show a short alien bent on conquering Earth poses as a human, and only one paranoid child knows his secret. More on iMDB: http://www.imdb.com/title/tt0235923
Most of the character is split in pieces which allows a lot of ball joint movement as well as proper multi-coloring with just a single extruder.
He can easily be switched to his human disguise by snapping in the human eyes instead of the alien eyes and replacing the antennas with the hair piece. There is also a 2nd head version in which he looks more relaxed. You could also print just a head without the body and use the head stand with it.
If you then want your Invader Zim to conquer our planet you might want to let him start small: http://www.thingiverse.com/thing:671647
ABS is strongly recommended since the ball joints need some flexibility to snap in the sockets. Most pieces also require a raft and support. The limbs and hands should be printed with high infill while for the other pieces a normal infill works fine.
It is a really complex design and the print needs to pretty exact so the ball joints fit in the sockets and remain some friction. Some force is required to push them in the ball sockets. All ball joints can then be rotated in position and then stay there. The wrist ball joint is the smallest but there is also a hand version which is lower arm and hand in one piece. Most limbs pieces are orientated laying to greatly increase their stability but there are also standing version which i included in the AlternativeStandingPieces.zip. It might make sense to print those with PLA.
There is a stand for him since balancing him with the heavy head is pretty hard. There is also a extra stand for just a head.
The limbs that don't have left or right mentioned in the file names can be used for both sides. Colors are also mentioned in the file names. I could not find the exact filament colors myself but got pretty close. Painting him will only work when you don't plan to use him as a action figure since the ball joints movement will peel off the paint. You could of course also glue everything in place. The rosy spots on his backpack are the only pieces that require glue and the human eye balls the only pieces that require painting.
- "Green Light"
- "Magenta Red"
- "Rosy Light"
- Grey (only the backpack main piece)
I printed mine with ABS and 0.2mm layer height. I used acetone vapor finish to get a smooth reflective look on most pieces. But there was the problem that some connections don't work so good anymore because of the acetone distortion.
