Wooden Base Snap Parts

Hi,

When setting up my Arduino for the first time, snapping out the wooden parts of the base, there was no explanation that they would be needed to create the spindle for project 09 later on. This is not mentioned in the book until page 100, which I find pretty amazing to be honest. Anyway, I was wondering if there would be a way to acquire these again, as in to buy the wooden base separately?

Thanks, Ben.
