Man, that's sick!! Rep for you - btw want to see it painted 
yes it could, i did a scratch built baneblade using card many moons ago which warped badly when paint went on to it, that was when i discovered plasticard.Wow amazing, how durable is it. Could the same thing be done with thin plasticard.
I printed out the treads twice. The first I left as a strip, then I cut a verrrry thin piece of cardstock to use for the link pins. I cut and glued them into position on the first strip. I then cut out the individual links on the second track and glued them down over the link pins on the first track. Finally, I cut out the squares and glued them down to the top of the links.pretty nifty...i'm thoroughly impressed! how did you do those treads? I've been struggling with those.
