Great model. Prints well in PLA on a raft and no support with a MakerBot Rep2.
ran 4 prints so far, I cant seem to get the webbing out
going to increase the retract on it for the next print
as of right now... i do not have a version in openscad... i will be more than happy to put one out when i get some time and get a copy of the software and play with it a little.... give me some other formats that would work for you and i would be more than happy to export and send!

Print with Raft and No support.
I have printed a half dozen on my replicator without a single fail.
Even one with multiple colors.

Very nice! I printed a couple of these on my Replicator in PLA, including one multicolor. (Yours look cleaner than mine. ) I don't have the coordination to change the filament while the extruder is moving, so I used pause. But for some reason ABS gives me a mess. It starts out OK, gets as far as finishing the ball, but the walls go awry. Tried this 3 times. I haven't used a raft, nor support, on any of these.
I use raft with no support and they work pretty good... i did have one fail a month or so ago... my second extruder head collided with one of the legs and broke it off which tells me i caught a rogue breeze and warped that leg... i think...
Great piece! Any chance you have an openscad file for this? I'd like to make some variants (fewer layers but thicker and more durable.) Now that I have seen it I can do it from scratch with enough work, but faster if you have a starting place fot me. :-)

I'm sorry about your Raft Problem Jazz .... I am using a "Replicator 1" .... my raft setting are either "with"... or "without" ... i don't mess with the default settings and it has always works ed fine with everything i have printed, so i am a little ignorant on modifying the settings.

My raft peels off very easy when finished. I did have a problem with one of the arms cooling a little during the print and warping up which cause my second extruder nozzel to break it off. My only failed print to this date. Keep playing with it sounds like you will figure it out. Post what you did so others won't have the same problem.
Any tips for removing the raft? raft settings?
I took 3 attempts (with a n00b calibrated printer) to get one to work, cooling fan/contraction caused ONE crack :-( but I can acetone weld that! But getting the raft off is impossible the way I 'rafted' it!
This looks awesome! going to try it out - what is the difference between the original and No. 2?
I added the smaller holes to #2 to reduce the amount of plastic needed to print the part and i think it makes it look better.
Also it will allow the finished part to stand up in a better display position without having to use the stand.  I have one of each on my desk, they both look good. :)
Thank you for the compliment.  It actually turned out better than i thought it would. When you peel the raft off the pieces will all be free and there is almost no post print cleaning or sanding.  I have one on my desk at work that is straight of the printer.  Everybody keeps asking if they can have one.
Very simple and you do not need to pause the print... that takes way too much time.  Simply snip the filament during the print about 1" above the extruder while it is printing.  Use sharp scissors and a very straight cut. use a flash light and watch the filament disappear  feed the new color right in behind it maintaining slight pressure for the fist 1.5".  thats it... just make sure the ends are "VERY" straight and it works fine.  
 How did you do the multiple colors? Assume filament splicing but how or what tool did you use to do it? Beautiful prints, especially the multi-color.
On The UP/Afinia printer, you can hit the Pause button, then press the Withdraw to remove the current filament.
Now press the Extrude button to feed the next filament. Then press Resume and you're done! :)
