The 4th Doctor's Sonic Screwdriver

Been too busy this year to come up with a new Halloween costume, so I'm revamping (regenerating?) my 4th Doctor costume. In the past, I've used the 11th Doctor's screwdriver (gasp!) and thought it was time to make the costume more accurate by making Tom Baker's sonic.  I've provided the sonic in two parts, so you can orientate them to get best print quality while minimizing overhangs/support material. Or you can do what I'm doing, and turn the base from aluminium using the attached CAD drawing.
