Mechanical Devil Fish Building Blocks Set
Mechanical Manta Ray Model Kit

The Mechanical Devil Fish Building Blocks Set is a 966-piece ABS construction kit that assembles into a detailed manta ray model with a working wing-swing mechanism. Turn the hand crank and the double wings sweep through a smooth, gear-driven motion that mirrors a real devil fish gliding through water.
Built-in double-winged LED lighting highlights the internal gears and structural detail, so the finished model works as a desk display, shelf piece, or engineering-themed decoration for a home office or studio.
Working Wings and LED Lighting

Each ABS component clicks together with a precise fit, guided by a step-by-step instruction manual. The gear train links the crank to both wings so the motion stays even and quiet, giving builders a hands-on lesson in mechanical engineering and gear ratios.
With a 24cm wingspan and 23cm height, this mechanical fish model makes a striking build for teens aged 14 and up, adult hobbyists, and fans of STEM building sets, kinetic desk toys, and animal-themed models.
