These plans include two model options.  One option has the lip of the horn mouth continue straight.  This is ideal for 3D printing.  The other option has the wrap-around horn mouth.  This option is for more advanced users of CNC machines. 

Shown below is the 3D CAD file with the straight horn mouth (no wrap-around)

Shown below the second option where the mouth includes the wrap-around.

Below is a list of files included in the order.
