do it jim… do it! 
as you know there are a few types of machines that work in slightly different ways. think the layered plastics one is cheaper than the powdered ones as it wouldn’t require fusing.
might sell my car for one. lol
I have look at a lot of different machine.
Would like to build one but the cheap one give poor result… so i have opted to use Shapeways.
Jim… if you buy one i will have a long list of parts to be made… LOL
Sorry, didn’t mean to be critical, just didn’t initially catch on what was being done. Interesting working with cables and all that. We have cables in the robotic arms of our da Vinci Surgical Robot (lower levels of DOF) as well as gearing.
Interesting stuff!

Yeah, but get a Dimension, not a Hobby machine!

Ok well i thought i might share the second part needed for the Pull-Pull system.
Pull-Pull Servo Case Adaptor.
This part will fit directly over the standard size servo (modelled with the HS645mg) and will allow the cable housing to attach to the servo though the horizontal holes as shown:
The rounded part helps keep the cable lined up on the wheel and will stop any tension failure should external forces be applied to the cable. for the applications ill be using it for, no such force would ever be faced. so its kind of over kill for me but in other applications this would be a perfect feature.
Eric is going to kill me no that i have started learning this CAD stuff. 
Designed using AUTODESK 123D!

That’s the end of my life… 
Eric is still perfecting the design but but here is a render of the latest casing adaptor:
Thanks Eric. your back in business. LOL
Looks great guys! 
Must say I like the last suggestion most. 
Are you both using Autodesk 123D?
I’m asking because I’m also interested in learning CAD…
No…!!!
Stop trying to learn that… 
I am using Solidworks myself.
I’ve been checking prizes and that software is very expensive… Probably have to look into other options.
Even those Dimension machines have visible stair stepping on the Y axis. I’m looking at the Objet25! It’s the only one that I found (under $20k) that has real looking true to life parts.
• 28-micron, high-resolution printing
• Tray size: 240 x 200 x 150 mm (9.45 x 7.87 x 5.9 in)
Yeah, that’s really fine!
The Dimension parts look real enough, are durable, and can be machine finished to remove the steps.
I wouldn’t have a problem working with the parts made on a Dimension, but then again I don’t use many plastic parts, and I prototype in aluminum. Big parts, I may lay out in 1/4" veneer plywood (scraps) if I don’t want to cut up a big piece of aluminum. Like, the 24" x 6" chassis parts for my RoboMagellan. These parts will actually be made in 1/8" fiberglass.
I hear a lot of guys prototype small parts in wax. I suppose that could work too (not for chassis parts!).

Solidworks is expensive but you’ll know were your money has gone. Autodesk123d is ok for making 3D parts, but its slow loading and does crash so remember to “Save” [size=150]+ its FREE![/size]
The left-hand, simple rectangular one.
Alan KM6VV
In fact that one is the more complicated one…!
Oh yeah, it’s got the lettering…
Alan KM6VV
Looks like the left-hand one would be easier to manufacture. How would you cut/drill the guide holes?
Those will be printed… so the shape have nothing to do in the complexity.
Only the CAD work was harder to do with the left one…
