Alternative cover for the Elm327 mini OBD-II bluetooth reader, with 2 air vents. The air vents also function as a grip to allow easy removal of the plug from the socket.Just pry the Elm327 mini open with a knife(e.g. Stanley FatMax break knife). The original hooks on the 1.5 version will probably break, if not remove them and use hot glue to secure the cover to the unit.Note: There seem to be 2 versions of this module, this print is for the old 1.5 version, which has the separated lip and is a bit taller than the 2.1 version. Will adapt the design to the 2.1 version once it is received.Update v2: Added the design for the 2.1 version and updated the pictures.Update v3: Added the design for the the single pcb version, which also should not need to be glued anymore.
