Kendama Ken (Blunt-inspired)

Create a precise, symmetrical, manufacturable 3D CAD model of an original modern kendama ken. The shape is a hybrid concept: compact and chunky like the Da Originz Blunt, with functional cup proportions inspired by the Grain Theory GT-TF. Do not copy branding or logos. All dimensions are in mm. MAIN: Tama: 62 mm Ken total length: 155 mm Target ken weight: 85–92 g BIG CUP: Diameter: 45.5 mm Depth: 12 mm Wall thickness: 2.0 mm SMALL CUP: Diameter: 39.5 mm Depth: 11 mm Wall thickness: 2.0 mm BASE CUP: Diameter: 43 mm Depth: 10 mm Wall thickness: 2.0 mm BEVEL: Diameter: 24 mm SPIKE: Diameter: 10 mm Height: 33 mm Smooth tapered point NECK: Diameter: 21 mm Length: 32 mm SARADO: Length: 76 mm Compact and chunky proportions HOLES: String hole: 1.0 mm Base hole: 17 mm diameter × 30 mm deep Both centered on the main axis Use smooth, rounded, manufacturable transitions between all sections. Keep the entire ken rotationally symmetrical and ergonomic. Make the cups stable and functional for stalls, lunars and taps. Maintain approximately 2 mm minimum structural wall thickness. Create one clean watertight solid CAD body. Make all dimensions editable/parametric where possible. Prioritize the specified dimensions and overall compact Blunt-inspired silhouette.
