I've been looking for a new form of entertainment at music festivals (aside from the music) and decided Bojutsu might be fun. I came up with an idea for a 3d-printable, collapsible, reconfigurable led staff a couple weeks ago and have since printed some pieces for it.
Here is a prototype segment printed with PLA using the Makerbot Replicator.
UPDATE:
See
this post for how to make your own collapsible LED bo staff!
