Tokoroa Control Tower from the xjet YT channel
Pylon V2 more accurate to real tower but will need support for the lower platform. V1 version of the pylon simpler to print but not quite as accurate to the real thing.
Printed it at 200% but on my first print the top railings didn't fully complete - seemed to be an issue with Slicer 2.4 if using ‘Print thin lines’ for some reason. REcommendation - don't select that option.
0.2 layer height, 5% infill for the hut, and increase perimeters/lines to 5 to get the strength for the girders.
