- Accurate Measurement: belt tension gauge designed especially for 3D printers belt measurement. It can achieve accurate measurements effortlessly across all belts, making adjustments smoother and more convenient. No more guesswork. - Single-Hand Operation: includes an STL file for a custom single-hand operation model for quick and hassle-free belt tension measurement. Please download the file on btt wiki / belter. - User-friendly Tension Converter: provides a table of belter value-tension converters to help convert readings into belt tension (N). Just enter the readings in the converter table to obtain the belt tension (N). The converter table is also on btt wiki / belter. - Easy to Read: an electric belt tension tool, providing clear and easy-to-read tension readings in 1 second. Use scenarios - Initial setup and calibration of a new 3D printer: use the gauge to measure belt tension across all belts for precise adjustments. - Post-maintenance or belt replacement: verify belt tension after replacing belts to ensure consistent performance. - Workshop or multi-printer maintenance: quickly check and standardize belt tension across several printers, using the STL model for single-hand use and the converter table for immediate tension readings.
