Sumobot Chassis

Description
Full disclosure.... this is a relatively difficult print and really pushes the limits of the build size. My makerbot was up to the challenge of the 2.5hr print and resulted in only minor warping but it was definitely a little stressful to watch.
I'm working on another (maybe better, maybe worse) version with multiple parts that slot together which would ensure more uniformity across makerbots.

Hi,
thanks for the 'bot, I printed it right away and liked it :)
One small thing: the HITEC HS-311 I am using fits verywell into the chassis (which with shrinkage and makerbot variabilityis not a small thing). The holes for the servo screws though don'tquite fit: they should on both sides be about 1mm closer to the servo.
And another thing: I wanted to scale down Your design so I could use
micro servos. Scaling itself works of course. But I'd have to change
the number and position of the holes for the servo screws and Google
Sketchup won't let me do that because of rounded surfaces.
Is there an earlier version of Your project, one before You did the
rounded surfaces?
Bye,
Christoph
Thanks for the offer, but I managed to figure it out. For some reason I had Tower turned on in skeinforge, and apparently it didn't like something in the model. I turned it off and now it works fine.
the only thing I can think that might be a problem is the size of the actual object. I used to have the problem a long time ago and I forgot how I fixed it. Is it possible that your using an old version of the skeinforge? (i'm using v005 with no problems)
I can upload my gcode if you want (i use really standard settings) but maybe you've tweaked yours.

Instructions
Install servos (standard servos... the dimension of mine is roughly 41x20 around the main body).
they were originally intended to be bolted in with 3mm bolts and nuts but hot glue is just as easy and works as well or better.
I still haven't given it a try with the motors because I only have 1 continuous servo on hand but I'll probably hack one of my standard servos and test it tonight.
The front slots should be great for adding IR sensors but I haven't tested the fit yet.

I'm having some trouble getting this to skeinforge. I keep getting "AttributeError: 'complex' has no attribute 'x'." Has anyone else run into this error?

This is awesome. I'm really excited to print it as soon as I get some spare time to do so.
Awesome. I can't wait to see your next version and for My classroom Cupcake CNC to arrive. I can see my students using this.
