Original Polydron Engineer Set

Introduce children to the fascinating world of gears, pulleys and mechanical movement with this 109-piece engineer set. Designed for hands-on STEM learning, the set allows children to build 5 different working models, exploring how simple mechanisms work through practical investigation. One model can be built at a time, making it ideal for focused problem-solving and step-by-step discovery.

The set includes gears with simple ratios of 8, 16 and 24 teeth, helping children begin to understand how gear size affects speed and movement. With baseboards, pulleys, struts, axles, linkages and framework shapes included, children can experiment with motion, force and mechanical design while developing spatial awareness, reasoning and engineering skills.

Perfect for classroom use or more advanced individual learning, this engaging resource supports the exploration of simple machines and encourages children to think critically as they build, test and refine each model. Work cards are included to guide learning and help bring key mechanical concepts to life.

Set includes: 2 baseboards, 2 small gears, 2 medium gears, 2 large gears, 1 small pulley, 2 medium pulleys, 1 O ring 410mm, 1 handle, 2 x 80mm struts, 1 x 90mm strut, 1 x 330mm strut, 6 stub axles, 8 stub axle connectors, 4 squares, 10 squares with strut hole, 24 framework squares, 4 double framework squares, 12 framework rectangles, 8 framework right-angle triangles, 8 framework equilateral triangles, 1 octagon with cut-out, 1 x 2m long cord, 1 x 3-hole linkage, 4 x 7-hole linkages, 1 cam and work cards
