The 653-piece wooden puzzle
The ROKR Gear Ball Challenge EGC01 is a 3D wooden puzzle made from 653 laser-cut plywood pieces. It is designed for builders aged 14 and older who enjoy mechanical model kits. The finished model functions as a rotating gear ball with marble-run elements. Assembly takes about six hours and creates a kinetic display piece.
Capacity and headroom for assembly
The kit contains exactly 653 wood pieces and requires roughly six hours to complete. It provides a substantial single-project build that occupies an evening or weekend. There are no expansion packs or modular add-ons, so the experience ends when the final gear meshes. Builders wanting a longer or repeatable build will need a separate kit.
Thermals noise and power draw
No batteries, motors or electronics are included, so the model produces no heat, fan noise or electrical draw during use. The only movement comes from hand-turned gears and gravity-fed marbles. It sits silently on a shelf as a decorative sculpture. Dust can be removed with a dry brush when needed.

Questions about this item
Will the 653-piece Gear Ball Challenge fit on a shelf that is 295 mm wide, 195 mm deep and 205 mm high?
The assembled model measures exactly 295 mm wide, 195 mm deep and 205 mm high, so it will occupy that full footprint on the shelf.
How can I confirm the gear transmission moves smoothly once I finish the build?
Turn the hand crank; the internal gears should rotate the three ball tracks continuously without binding, showing the kinetic mechanism is working as designed.
Are glue, tools or batteries included with the 653 wooden pieces?
The kit contains only the laser-cut plywood parts and printed instructions; no glue, tools or batteries are supplied.
