The prompt
Create a flat 2D sheet-metal chainsaw felling dog profile extruded to a uniform thickness of 3.175 mm (1/8 inch), with overall bounding dimensions of 210 mm in height and 115 mm in width. 1. FRONT EDGE SPIKE GEOMETRY: - Top Spike: Extends forward and upward at a 40-degree angle relative to horizontal, with a straight top edge length of 55 mm terminating in a sharp tip with an R0.5 mm fillet. - Upper Gullet: A smooth, deep concave arc with a radius of 22 mm sweeping between the top spike and middle spike. - Middle Spike: Prominent horizontal spike extending forward by 70 mm, with a straight upper edge and a hooked lower curve, terminating in a sharp tip with an R0.5 mm fillet. - Lower Gullet: A smooth concave arc with a radius of 20 mm sweeping between the middle spike and bottom spike. - Bottom Spike: Extends downward and forward at a 50-degree angle relative to horizontal, with a length of 45 mm terminating in a sharp tip with an R0.5 mm fillet. 2. REAR MOUNTING EDGE GEOMETRY: - Rear Contour: A smooth inner concave sweeping curve with an R145 mm radius designed to wrap around a chainsaw sprocket housing. - Upper Mounting Tab: Features a rounded ear with an R8 mm outer radius containing a 6.5 mm diameter circular thru-hole (for M6 bolt), centered 15 mm from the upper-rear edge. - Lower Mounting Tab: Features a second rounded ear with an R8 mm outer radius containing a 6.5 mm diameter circular thru-hole, positioned 75 mm directly below and offset 12 mm inward relative to the upper hole center. 3. CENTRAL WEB & CUTOUT: - Web Structure: Flat planar body connecting the rear mounting flange to the front teeth with a minimum material web width of 35 mm between the gullets and the rear edge. - Center Cutout: A vertically oriented stencil cutout reading "WCS" in block lettering (font height 25 mm, width 8 mm, cut completely through the 3.175 mm thickness), centered horizontally and vertically on the central web section.
