UGEARS has over 90 unique, high-quality wooden mechanical model kits that have been bringing generations of families together since 2014. Through 3D puzzles or model kits, we provide hands-on experiences for children and adults of all ages to create and assemble working mechanisms without the need for batteries or other external power sources.Many of our wooden model designs are inspired by real-life prototypes, while others are reimagined based on history. The engineering and production of each design are unmatched, using cutting-edge technology to cut every piece of plywood. None of our models require glue or any special tools to complete assembly; all gears, cranks, and rubber bands work through gravity to make them move. We offer kits covering a wide range of interests, such as game board enthusiasts, vehicle and aviation models, palm-sized mini kits called U-Fidgets, STEM kits that integrate science, technology, engineering, and math, as well as coloring model kits for children aged 5 and up.
