## Description

UGEARSSTEM Lab 3D Puzzle - STEM Set - Wooden Model Kit - Creative STEM Toy with App - Mechanical Model Wooden Construction Kit - 3D Wooden Puzzle for Adults and Children 8+ (Curvimeter)

## Features

- The Curvimeter model kit is a miniature card knife, also known as the opisometer. This mechanical toy measures the length of arbitrarily curved lines and helps to calculate the distance between points on a map more accurately than a ruler or compass. You can do homework or hike in remote areas without Internet access. Like other Ugears building kits for adults and children, this learning toy has an iconic design and is easy to use.
- Educational entertainment: UGEARS STEM LAB helps children to be educational and have fun. Our construction toys show the basic concepts of science, technology, engineering and mathematics and help children explore things in the real world. Conveniently putting things together is fun and easy as each mechanism is fully explained. You can put together UGEARS Science kits for children and adults yourself or as a group project.
- LIFETIME SKILLS AND KNOWLEDGE: This new collection of 3D puzzles and construction toys is unique as they are commonly used mechanisms. In addition to the Curvimeter, discover other four of our STEM models: the pendulum, the manual transmission, the differential gear and the counter. Our science kits encourage children to focus and persevere. Everything you need is in the box; no gluing or cutting is required.
- Beautiful gift box: with a practical cardboard packaging, the UGEARS Science Kits (construction toy package) are an exclusive gift for children and adults. Our STEM toys stimulate the desire for more knowledge and provide hours of fun. All of our mechanical puzzles for adults and children transform into beautiful decorative pieces.
- Interaction with mechanical models: improve your editing experience with the new stunning UGEARS augmented reality app. Point your tablet or mobile phone at a fully assembled STEM laboratory model, and the app shows you different uses of the mechanism you just created. Go to the limits of your reality and order the UGEARS STEM Lab 3D puzzles now
