link to the bicycles I always wanted to create a bicycle model in HO scale. There wasn't any scale model of the old Swiss military bike. Most of the bikes available at this scale are etched out of a thin sheet of brass and have to be folded in shape. They are quite difficult to build. The 3D printed model only has to be painted, since the "assembling" already happened in the printer ! This model was quite tricky to create, because I had to thicken a lot of features while keeping the resulting model recognizable.
