This is a 3D printable injection mold designed for producing soft plastic lures inspired by the legendary Frapp Geko — a mid‑proportioned vibrotail with a characteristic scaly surface and a rounded, drop‑shaped tail heel. The mold features a single cavity for efficient 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:

Single cavity for the 160mm (6.3") Geko profile

Scaly textured body with pronounced plate‑like relief creating powerful hydroacoustic vibrations and enhanced visibility in water

Distinctive rounded, drop‑shaped tail heel that activates at minimum retrieve speeds — works effectively even on the slowest retrieves

Optimized runner system for proper material flow

Venting channels along the 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
