Here's a handy little cardboard spool you can use for your MakerBot filament. I designed it for a thicker cardboard than pictured, but all I had around when I was inspired were some pizza boxes.As posted on my blog http://charlespax.wordpress.com/2010/01/08/cardboard-spool/See it in action as part of the future Bowden filament drive box http://charlespax.com/2010/01/26/makerbot-filament-box-and-drive-mechanism/The latest version can be found in subversion at http://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.
