Six colorful, wooden gears of varying sizes fit together as a flat puzzle but also stack to make sculptural towers. Each gear is labeled with its color name in English, Spanish, French and German and the puzzle includes a 7.75”x7.75” wooden tray for display and storage. The Gear Stacker Puzzle is recommended for ages 2 and up.
manufacturing and tolerance issues
Posted by Jean koster on 28th Mar 2017
Manufacturing tolerances are too tight. Adult can nor easily assemble or disassemble elements. A toddler, skilled in assembly of other similar toys, has serious difficulties which leads to frustration and rejection of the toy. I need to machine the rings to get larger tolerances and easier fit with more play between rings.
