Gravitrax Junior bridges

In order to create nice Gravitrax Builds, you need long bridges. I have created bridges with a length of 2 to 6 slots, with a height of 10mm (standard height of the lowest raiser). The bridges with up to 5 slots can be printed on the 256mm buildplate, the 6 slots bridge needs a bigger printer. No support needed!The 5 and 6 slot bridges tend to bend a little so make sure to print them strong enough (4 walls and over 50% infill).
