A plurality of filaments are received in the respective filament reception channels of the filament reception fasteners. For each of the filament reception fasteners, the fastener head and the shaft are arrayed along a fastener longitudinal axis, and the filament reception channel extends perpendicular to the fastener longitudinal axis. Washers are located on the shafts of the filament reception fasteners between the nuts and the support disc. The filament reception channel includes exterior walls which are arrayed in a polygonal pattern.
