Snap Fit Gauge is a local calculation tool for plastic part prototyping, model making, and early structural sketching. You can record snap-fit type, material thickness, cantilever length, hook height, assembly clearance, and chamfer parameters, then quickly get suggested deflection, reserved clearance, engagement depth, and risk notes. The app includes common snap-fit scenario templates and supports project saving, unit switching, dimension reuse, error marking, and local history. All data stays on your device. No account, internet connection, or data collection is required, making it suitable for desks, workshops, and offline environments.
