HBP Wedge Removal Tool Remix

I really liked the original tool, but I wanted it to be a bit longer for my fat fingers, so I made some slight modifications to the scad file to allow specifying length and width separately (the original file used the same value for both).
Note: The thickness is specified as a negative number so the piece will lay flat. There's probably a way to fix that without using a negative number, but I just built my first printer and started learning OpenSCAD last week, so this is all new to me.
