billiard training block 3d model

Create a solid rectangular billiard training block. On the front face, apply a true half-circle cut-out (180°) that directly removes material from the block, exactly like a half circle profile cut, not a recessed pocket, not a tunnel, and not a curved ramp. The half-circle cut: Matches a standard billiard ball diameter (~57 mm) Touches the bottom edge of the block Fully cuts into the body Front face remains flat, with a clean geometric cut Design constraints: Solid body Minimalist, geometric design Slightly rounded outer edges No internal cavities or ramps Technical: Real-world scale Clean, watertight mesh 3D-print-ready Matte plastic material Output: Simple, precise, functional training aid geometry.
