A 3D-printable flat packing tape opener with a comfortable finger ring and a sharp curved cutting edge. The ring grip wraps around a central bore, and a long curved tail with a concave blade hooks under tape and slices it cleanly. Adjustable parameters control ring size, bore diameter, blade radius, and cutting angle for customized fit and sharpness.
