HO-scale signal gantries

HO scale signal gantries The model shown is 390mm wide and designed to span 4 tracks, but the dimensions can be adjusted to suit any requirements. There are 3 types of supports: a straight version with an integrated ladder, a central version for a long crossbeam, and a left-hand version with a smaller base. An accompanying video explains the assembly process and how to modify the dimensions using Fusion 360, based on the provided .STEP file. You can also adjust the dimensions by changing the scale within your slicer—provided the required change is minor; otherwise, you will need to use Fusion 360 as demonstrated in the video. The gantry is equipped with a 4-aspect signal head, which can also be modified. The model shown was printed on a Bambu Lab A1 Combo using basic PLA.
