A modular meter roller for an agricultural metering system. The modularmeter roller includes a first roller segment that couples to and rotates witha shaft tometer flowable particulate material. The first roller segment includes a bodythatdefines an aperture. The aperture receives the shaft and the aperture definesaplurality of vertices. A first plurality of fins extending radially outwardfrom thebody. The first plurality of fins defines a first plurality of grooves in thefirst rollersegment that receives flowable particulate material. A vertex of the pluralityofvertices of the aperture is offset from a longitudinal axis of a fin of thefirst pluralityof fins.
