Originating from http://www.thingiverse.com/thing:38952, this adaptation replaces quarters with washers for weight in the belt. The Tension_Gauge.stl file, sourced from thing 38952, is incorporated to be imported by openscad files. Simply print hanger and washer components, then attach the washer to the hanger's bottom (use glue if desired). Fill both washer halves with 1/4 inch washers for operation, observing how far it hangs on each belt.
