Platform insert for bowl, bowl with platform, and methods of using the same

A filament bowl comprising

• a filament platform, the filament platform comprising:
• a platform body having an arcuate shape with an outer perimeter in the form of a minor arc, the platform body having a front end, a rear end, a bottom, a top, a first lateral side, and a second lateral side, wherein the first and second lateral sides extend vertically between the bottom and top, the front end extends laterally between the first and second lateral sides at a radially-inward perimeter between the bottom and top, and the rear end extends laterally between the first and second lateral sides at a radially-outward perimeter between the bottom and top;
• the platform body comprising a plurality of stages that protrude in a radially-inward direction, with at least one stage in the plurality of stages being defined at least in part by a first upper surface and a second lower surface, and a plurality of recesses that are open at a radially-inward side of the platform and extend into the platform body in a radially-outward direction, with at least one recess in the plurality of recesses being defined at least in part by a first curved radially-outward surface and a second upper surface, the plurality of stages and recesses forming a plurality of filament channels in the platform body, wherein
• the plurality of stages and the plurality of recesses are arranged in a recess-stage-recess sequence, with at least one sequence in which the second upper surface of a recess corresponds with the second lower surface of an adjacent platform and the first curved radially-outward surface of the recess has a radially-outward most point at an upper end of the curved surface, and
• stages in the plurality of stages and recesses in the plurality of recesses extend laterally between the first lateral side and the second lateral side such that the arcuate shape of the platform body is circumferentially centered around a reference axis that extends in a top-to-bottom direction, perpendicular to the lateral extension of the stages and recesses, with the reference axis passing through a point at or forward of the front end of the platform body.
