ZITIANYOUBUILD MOC-41121 Archimedes Trammel 347 Parts

Archimedes Trammel 347 Parts

This building set contains 347 pieces that assemble into a working Archimedes trammel, a mechanical linkage known as a do-nothing machine. It is aimed at adult hobbyists and older children who enjoy engineering models and kinetic sculptures. The finished mechanism demonstrates elliptical motion without performing a practical task.

100% LEGO Compatible Bricks

The 347 parts are moulded from ABS plastic and are fully compatible with LEGO and other major brick brands, so they can be mixed into existing collections. The piece count provides enough parts for the complete trammel mechanism with a few spare elements for experimentation. Complex motorised expansions would require additional Technic gears and axles not included in this box.

ABS Plastic Durability

Moulded from BPA-free ABS with smooth edges, the bricks resist breaking and bending during repeated assembly and disassembly. No electronic components or moving motors are present, so the model runs silently and draws no power. The mechanism operates by hand cranking, producing only the quiet click of plastic gears meshing.
