Interior Width Gauge

This 3D model set features a series of interior gauges designed for precise and efficient measurement of box interiors, ideal for creating custom inserts. The set includes three gauge variations to measure widths between 10–20 cm, 20–30 cm, and 30–40 cm. The main body of each gauge is divided into 100 mm increments, with a 100 mm sliding insert for ease of use. To operate, insert the sliding component into the main body, place the gauge inside the object to be measured, extend the insert until it touches both sides, and lock it in place for accurate measurement. For tapered items, measurements can be taken at the bottom, middle, and top to accurately replicate angled sides. This design ensures fast and reliable measurements for a range of interior dimensions.
