The prompt
Design a 3D-printable replacement brush head compatible with an oscillating-rotating electric toothbrush base (Oral-B style standard drive shaft fitting). Key Specifications: 1. Base & Stem: - Standard hollow cylindrical stem with internal drive mechanism connection (semi-circular notch/keyway) fitting an Oral-B motor shaft. - A neck tapering smoothly upwards to a circular head disk. 2. Functional Head & Attachment Mechanism: - Instead of conventional synthetic nylon bristles, the circular top face features a natural wood retaining system. - Concentric arrangement: An outer circular ring (diameter ~11 mm) and an inner concentric circular ring (diameter ~5 mm). - Retention system: Inside the annular channel between the rings and within the central ring, integrate an array of rigid, sharp micro-barbs (pointed retention hooks) angled downward/inward at 45 degrees. - Purpose: These mechanical barbs are engineered to grip, pierce, and securely anchor a replaceable slice/disc of natural miswak root (Salvadora persica) under high-speed oscillating torque without slippage. 3. Geometry & Tolerances: - Flat bottom floor on the head with drainage micro-holes for water egress. - Retaining outer rim with a slight inward chamfer to guide the wood disc into place. - Clean parametric geometry, sharp retention ridges, and production-ready mechanical clearances.
