About this Product
improved extruder drive wheel for Cupcake CNC. This adds a radiused, recessed edge to better center the filament, and a chamfer on one side to permit easier bearing installation. It is a little thicker, and because the standard acrylic one is brittle, the standard part is easy to break in use. Suggest making it in stainless steel. for a super strong part.
