See it in action as part of the future Bowden filament drive box charlespax.com/2010/01/26/makerbot-filament-box-and-drive-mechanism/
The latest version can be found in subversion at svn.makerbot.com/users/charles/bowden/ .
EDIT 2010-03-21: I added a divider to the files. Thanks, Kevin. I also decreased the size of the hole that secures the filament to better grab the it.

If you don't have access to a laser cutter, you might want to look up one of your local corrugated board suppliers or a box manufacturer. Most plants have a designer on staff with a cutting table. A cutting table can cut from DXF files with minor conversion, or directly from an HPG or ACS file. If the designer is a bit of geek (very likely), he or she may cut it for you for free from scrap stock if you let them use the file how they want.
Also, it's called "corrugated board", "corrugated paperboard" or just "corrugated" when it has the liner paper(s) combined with a fluted or corrugated paper.
Time goes by - and we noobs find excitement in the discovery. Thanks for you post. Pretty neat. I'm cutting on the MakerBot box soon. :)
I love the simple things like this. :)
On its inspiration I made a simple stand to support spools like these over a Mendel, so long as the diameter is under 12 inches.

Now you'll have a top hat crown thing. Place your filament roll over the barrel and put on the other flange. Again, tape helps.
A 10 mm shaft through the arbor hole and you're ready to print. Well, you'll probably want some sort of mount for this. It's coming...
