Shark-Attack Pack: Wearable shark fin for swimming

Take playtime to JAW-some new depths with the Shark-Attack Pack – a wearable 3D-printed shark fin for kids, adults, and misunderstood ocean villains everywhere.

Perfect for bath time, pool parties, or confusing the family dog. 🦈

This fin comes in three parts:

• Fin A (male)
• Fin B (female)
• TPU bottom plate for extra comfort against the back

Fin A and B snap together securely — glue optional but available for the overly cautious. 

Thread your own straps through the two built-in holes to transform any swimmer into the ultimate bath-time predator.

Print tip: Use gyroid infill so that if water gets inside, it forms a single internal chamber that drains smoothly — because no one wants a soggy shark.

The stls are 210mm at the base of the fin (excluding the bottom plate) but the project files are scaled by 120% which just about fits a A1 plate. (246x246mm)

Be careful when downscaling as I haven't tested the press-fit of the pins.
