 +Scaled to 3mm - warning, this is the one I used but is small and difficult to assemble.

 +==== Assembly ====
 +
 +... Was a bitch and took about four days elapsed made up of multiple assembly attempts rolled back. There are a few pointers to help scattered around the 'net but I didn't find any of them particularly helpful. The windy nature of the sculpture and the way it keeps weaving back inside follows a specific pattern which isn't completely apparent until you've made a few costly mistakes.
 +This needs more pictures.
 +
 +==== Lessons ====
  
 +  * Don't trust plans off the web, they often have small or even significant problems.
 +  * It was too complicated to glue while assembling and too fiddly not to.
 +  * This design at 3mm clearance was not very forgiving. A couple of small mistakes and I no longer had room to insert the last two pieces through the sculpture. I resorted to snapping these in half and poking the halves in from either side.
 +  * I should have used a nicer glue than superglue!
 +  * Bluetac is no substitute for glue.
 +  * Sticky tape is no substitute either.
  
 +==== In Future ====
  
 +  * Try a larger copy with pieces double the size but reduce size of the teeth to match 3mm material.
 +  * Try perspex with LED lighting hidden inside, contacting and lighting separate arms of the sculpture
 +  * 6mm clearance but have each section made from two 3mm pieces of perspex, the inner piece as colored perspex and the outer piece in clear perspex. Together they act like a single 6mm thick piece to match the teeth size.
