Description
This is a simple tool to put in a hand-drill to twist pairs of wires to reduce EMI (electromagnetic interference), most notably though cross talk among wires that run alongside each other.
It was designed in about 60 seconds in TinkerCAD. You can copy and edit this design by following this link:

Printed by an Ultimaker, for Ultimakers! We pre-twist the 6 endstop wires. This way, Ultimaker builders will save some time with assembly.
This video shows how this part has undergone and passed extreme stress tests:

Instructions
1. The current one is for pretty fat wires (1.5mm diameter), but also works for smaller ones. But you can adjust its size to fit fatter wires too.
2. Print it.
3. Do the twist!

does the round handle print well in this orientation?

The handle was reasonably round at the bottom. I designed in some little struts to support it (which you cannot currently see), could've let Skeinforge generate it too. It printed fine, and we stress tested this part MANY MANY times, allowing for the nice 'dreadstops' (as in endstops and dreadlocks) picture :)

Maybe not - but this orientation looks like what you want to avoid the weaker vertical axis.

Hey, I see you can print with wood too already? The Ultimaker really is a revolutionary machine! :)
Next up is printing in "air". Revolutionary, cheap and abundant! Too bad that 1st of April isn't for another year (just about). And of course Shapeways did something similar... http://www.shapeways.com/blog/...
