Four Tile Bridge

This a shorter version of the file tile bridge. This one is four hexes long and can be used in a variety of different ways. In my Gravitrax I've used them as: a bridge between two columns and placed tiles suspended above other track routes below, a platform for arranging transfers in a line, and as a cantilever for holding tiles in mid-air to enable routes that would otherwise high columns. I've provided photos for these examples with this design. The four tile bridge can only be printed on an A1 or bigger (ie 256mm by 256mm). The bridge uses x grams of filament and takes about y minutes to print. I've used tree supports to ensure that the tile holder sections are well formed.
