The prompt
Design an Alesis Nitro Max drum kit cymbal arm clamp insert wedge (spacer block) for 3D printing. The part is a semi-cylindrical clamp insert used inside an electronic drum rack cymbal mount. Overall dimensions: 30mm diameter, 30mm width, 22mm height. Features a flat/sloped rear face angled to fit inside the rack clamp housing. Includes a vertical 12.5mm through-hole/channel along the front face to fit a standard 12mm knurled Alesis cymbal rod. Includes a horizontal 8.5mm through-hole intersecting the center to allow an M8 clamping T-bolt/wing nut shaft to pass through. Top edge features a small 20mm x 4mm retention lip (3mm height) to lock into the outer clamp housing. Outer Geometry: Base Cylinder Diameter: 30.0 mm Total Height: 22.0 mm Cutout Angle / Flat Rear Face: Sloped rear profile at ~45 degrees Vertical Rod Channel (Cymbal Arm): Hole Diameter: 12.5 mm (Standard 12mm rod with 0.5mm 3D printing tolerance) Orientation: Z-axis through-cut Horizontal Bolt Hole (Clamping Screw): Hole Diameter: 8.5 mm (Standard M8 wing bolt clearance) Orientation: Y-axis through-cut Retention Lip (Top Alignment Tab): Width: 20.0 mm Depth: 4.0 mm Height: 3.0 mm
