A playful fish-shaped massage roller with soft TPU spike wheels designed for smooth, relaxing pressure across the body. Compact, satisfying to use, and fun to print.

Full Description

This fish-shaped rolling massager is designed purely for relaxation.

It doesn’t try to reinvent massage science — it just feels good to use.

The body, pins, and caps are printed in PLA for strength, while the wheels are printed in TPU so the spikes stay soft and comfortable. Unlike hard plastic rollers, the TPU wheels apply pressure without scratching or hurting the skin.

The design is lightweight, compact, and works great on the back, shoulders, arms, legs, or anywhere you want a quick rolling massage. The balanced 4-wheel layout provides smooth, even pressure while rolling.

Assembly is simple and only takes a few minutes (see assembly GIF), but it does require glue.

Use small amounts of glue between the caps, pins, and wheels during assembly to keep everything secure. Once assembled, the wheels roll smoothly and provide even pressure across the surface.
