This model is based upon the nominal dimensions of Stanley (R) Utility Blade No.1992 (11-921). Actual blades may vary in tolerance, as shown in Patent Drawings.
I have not attempted to print this, but I've been using it to assist in the design of tools that incorporate these blades. Whilst the edge of the blase is replicated, I've not replicated the usual stamped details:
