fingertip prosthetic sleeve 3d model

Design a realistic ergonomic fingertip prosthetic sleeve (thimble style) for a person without fingernails. The design must be a soft flexible fingertip cap that fits over the distal phalanx. Internal cavity slightly tapered (0.5–1 degree) for a snug anatomical fit. Internal diameter approximately 14–18 mm (neutral adult size). Wall thickness uniform 1.5–2 mm. Bottom edge rounded and smooth for comfort. Exterior surface smooth and natural fingertip shape. On the top surface include a flat mounting platform (approx. 10–12 mm long) with a shallow rectangular slot (0.8–1 mm depth) for inserting a separate rigid nail piece. The slot should allow friction-fit assembly. No decorative elements. Clean watertight mesh. Optimized for TPU 95A 3D printing. Medical-style minimal design.
