This is a 3D printable injection mold designed for producing soft plastic lures inspired by the legendary Reins Rockvibe Shad — a unique ultra‑narrow vibrotail with a flattened elliptical body and segmented paddle tail that creates high‑frequency vibrations even at slow retrieves. The mold features two identical cavities for efficient small‑batch production and is optimized for FDM printing (Bambu Lab, Prusa, Creality, etc.), while also being compatible with SLA/DLP resin printers.

Injection Specifications:

Injector diameter: 16mm (compatible with standard hand injectors and small injection machines)

FDM Printing Recommendations:

Layer height: 0.08mm maximum for best surface quality and detail reproduction

Recommended material: PETG or any filament with a higher temperature resistance than PLA (ABS, ASA, Nylon, PET‑CF, PC, etc.)

For large models (over 5 inches / 125mm):

Wall loops (perimeters): 12–15 lines

Top solid layers: 10 layers

Bottom solid layers: 10 layers

Infill density: 10–20% (adjust as needed for strength vs. material usage)

Recommended orientation: cavity side up for best surface quality

Can be printed without supports or with minimal supports depending on orientation

For best results, print with a brim or raft to improve bed adhesion

Mold Features:

Two identical cavities for the 140mm (5.5") Rockvibe Shad profile

Unique narrow flattened body profile — elliptical shape with indentation at the head for secure jig rigging

Segmented anterior section with three distinct body segments transitioning to a ribbed posterior tail section

Paddle tail with a distinctive boot‑shaped flange that creates intense high‑frequency vibration and water displacement

Robust tail connection — the tail and body share similar thickness without weak transition points, extending lure life

Optimized runner system distributing material evenly to both cavities

Venting channels along each cavity for air escape during injection

Alignment pins and matching holes for consistent mold closure

Designed for use with hand injectors and small injection machines

Compatible with plastisol, soft PVC, and other soft plastic materials

Thick, durable mold geometry designed for repeated use
