These printables fix a well-known design problem that exists with Scott's EdgeGuard Mini and other various versions of the broadcast spreaders. The design issue is the impeller sits below the wheels. This prevents the fertilizer from being thrown above the wheels of the spreader. The fertilizer meant to be flung far away, now gets stuck at the hollow wheels then drop straight down causing the stripes.
Print two spacers, two wheel covers and one shaft riser.
