600 mm radius curve track for 45mm gauge tracks, common used in Garden railways (16mm and LGB scale).
There are track holders for printed sleepers och wooden sleepers.
The STL files is for a complete track, track you assemble by your self and a complete track for dual extruder printers.
You must print 6 tracks for 90 degrees curve.
I Have not printed this track, but most parts is from 765 radius tracks, so i can't se any problems to print this track.
It should be easy to print this track, and you only need support on the complete tracks.
All STL files has been tested in Netfabb.
All STL-files named "dual" are for dual extruder print.
I have printed my tracks with PLA at 0.3mm layer height and 30-50% infill. (30% is enough, 50% is on the safe side)
