Replacement part for that little plastic part that goes on shipping tape guns. Part is 2" wide and 3" tall and M4 screws are about 30mm on center. The original part is flexible; this one is stiffer but seems to work fine (and probably better).
Since it's used in a production environment it's getting tested; will post refinements as they're made. Original part lasted 15 years so maybe this one will never break...
