Any chance you could release a version of this puzzle without the handlebars as I feel they just to the price with the extra material. It seems like they could easily be replaced by stickers showing where the pieces are connected. They look nice and it adds to the fun of the puzzle but they don't add anything from a functionality standpoint as far as I know.
They contain the six quarks required to form the invisible force field. Wthout them it would be cheaper, but the quantum structure of the universe would begin to unravel. And that's bad.
