This ist my first little attempt to design a R2-D2.
I haven't created any 3D-object within the last two years so I'm not really concerned with it right now.
Particulary I have no clue of how to draw on the cylindric part, maybe I should check out some other CAD software.
This first sketch was done with Solid Edge v20.

Any comments appreciated!

The next step is now to build R2 in single parts that can be printed(regarding the problems with the overhangs too) and then glued together. I started with the dome, but I have to admit I got a little lazy in the end cause doing these spherical details is quite laborious in solid edge or I just didn't figure out how to do it right yet.

It looks like the .stl-Dome got somehow mirrored from left to right, don't know why.

Can you post the native file? What did you create this in?

I made R2 in Solid Edge V20, just because that was the only CAD-software I hat at least a slight clue of how to use it. http://dl.dropbox.com/u/14208858/R2-D2.ziphttp://dl.dropbox.com/u/142088...

I'm trying to print this, but overhangs don't work on the makerbot. Right now I've cut it in half and will try to print and glue it back together

Wow! Thats something i didn't expect, espacially not in this early state of the design.

When I have figured out how to shape the cylindric parts, would it be helpfull if I split the design in some parts before uploading? You cut it in half right through both legs?

Yes, my wife really like it so I thought we'd give it a try.

Okay, I screwed up the first print because I tried to print half of the legs unsupported. Once the bottom of the legs started printing it torqued the small part that was in contact with the build platform off.

It occurred to me to print the dome by itself and the rest of the figure upside down
. I'll probably try this in the evening.

I would suggest putting a full model up and then also adding pieces to print out. It might turn out to get really good detail you'll have to take the legs off and print them separately. Also there are a few folks on here with honest to goodness rapid prot
otypes that can print anything you can dish up!

Here's how I split it up and printed it out. note that some of legs had slight overhangs/jumps when printed upside down that left some plastic to float in space. I can clean most of this up, but something to consider.
