The New 3D Printing Thread

Curious if you tried printing the tracks whole (not split lengthwise) and have two pieces instead of four so they don't have to be sandwiched glued together or is that not possible?

My thinking was that if you did it that way the underside would need to be literally full up with a support mesh, better to have a nice clean flat surface on the printbed.  Nigels would know better than me though.
