On your (motor) bike!
Ola.ecmodels has released an .stl for the EW English Norton Big-4 Motorcycle with sidecar, or the “Model 1”, which was made from 1907-1954. Designed to carry two or three men plus their fighting equipment over very rough terrain. It was used for reconnaissance and carrying ammunition to the front line troops. Great for a motor-cycle combo from Sea Lion or a Battle of France Motorcycle section.
