This was an experiment using some great colours of Faberdashery PLA filament and a different method to combine colours.
Along with the joined coloured filaments I also designed cut-out sections and objects to fit into the voids, after printing these separately these were heated with a hot-air gun and pushed into the spaces, this was not as easy as I had expected due to the fact I made them sized to fit, really they need to be slightly smaller as they would be so much easier to join when warm and soft.
You can see it printing in this video here - http://www.youtube.com/user/RichRap2011#p/a/u/0/lrJPJDvobFI

Print out all the parts and join them together, I used a heat-gun and melted them all to fit.
If you want the striped effect you need to join lengths of filament together - see my filament joiner -
If you don't have someone special with an 'A' as their name, you may want to edit the sketchup files.
