A modular meter roller for an agricultural metering system. The modular meter roller includes a first roller segment that couples to and rotates with a shaft to meter flowable particulate material. The first roller segment includes a body that defines an aperture. The aperture receives the shaft and the aperture defines a plurality of vertices. A first plurality of fins extending radially outward from the body. The first plurality of fins defines a first plurality of grooves in the first roller segment that receives flowable particulate material. A vertex of the plurality of vertices of the aperture is offset from a longitudinal axis of a fin of the first plurality of fins.
