This is a 3D printable injection mold for producing soft plastic lures inspired by the legendary Frapp Geko — a scaly vibrotail with delicate action, designed in collaboration with Russian pro angler Andrey Pitertsov . The mold features a single cavity and is optimized for FDM printing (Bambu Lab, Prusa, Creality, etc.), while also being compatible with SLA/DLP resin printers.

The Geko 10(250mm) is the largest size in the series, weighing 103g and coming 1 piece per pack . It features a characteristicscaly" surface with overlapping plate-like relief, a rounded drop-shaped tail pad, and virtually no rolling — only the tail plays actively even at minimum retrieve speeds . The large models are not simply scaled-up versions; they feature a special tail pad design with less plastic relative to the body and a characteristic cutout, preserving elegant and light action even at this size .

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 250mm (10") Geko profile

Scaly textured body with pronounced plate-like relief creating powerful hydroacoustic vibrations and enhanced visibility

Drop-shaped tail pad with characteristic cutout for large models — preserves light action despite size

Minimal rolling action, concentrated tail play — ideal for slow retrieves and delicate presentations

Longitudinal hook grooves on back and belly for offset hook and jig head rigging

Durable, dense silicone geometry designed to withstand multiple predator attacks

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
