Mechanical Crab Built From 700 Metal Parts

This crab model kit assembles into an articulated mechanical crab from more than 700 precision cut metal parts. The translucent coloured carapace leaves the gearwork, pistons and wiring visible, so the finished 3D metal puzzle reads as a machine rather than a plain figurine.
Parts snap and screw together with the included tools, with no glue or paint needed. Expect 8 to 14 hours of build time spread across several sessions.

Poseable Legs And Working Pincers
Both claws open and close, and the eight jointed legs hold a pose, so the assembled crab can be restaged on a shelf. The eye stalks and shell plates are separate machined parts, which is where most of the piece count goes.
Two colourways are available, a crimson red shell and a teal green shell, both over the same stainless steel frame and brass gear detailing.
Key Features
- Over 700 precision cut stainless steel and alloy parts with brass gear accents
- Translucent coloured shell panels that leave the internal mechanism on show
- Poseable legs, articulated claws and movable eye stalks on the finished model
- Screw and snap assembly, no glue or paint needed, basic tools included
- Two colourways, crimson red or teal green, with identical construction

3D Metal Puzzle For Adult Model Builders
Metal puzzles for adults sit somewhere between a model kit and a desk sculpture, and this one leans hard into the mechanical side. It suits builders who already finish 500 piece plus kits and want something with moving joints at the end of it.
The finished crab works as sci fi desk decor, a study or workshop display piece and a birthday or Christmas gift for engineers, model collectors and steampunk fans.
