exiftool - rename using model only - not maker

Question

I want to rename my files to include the camera model, but the full tag includes the make as well.

exiftool.exe -d %Y-%m-%d_%H%M%%-c.%%e  "-filename<${model;}_$CreateDate" -r DIRECTORY

Creates:

NIKON D750_2019-03-07_2156.nef
KODAK DC280 ZOOM DIGITAL CAMERA_1999-05-31_1200.jpg

Ideally, I would like only "D750" or "DC280" in the file name.

Is this something I can do in exiftool? Or would this be better done in some other 'renaming' program? Any recommendations?

There is no 'better' tag to use:

exiftool -s "KODAK DC280 ZOOM DIGITAL CAMERA_1999-05-31_1200.jpg"

ExifToolVersion                 : 11.38
FileName                        : KODAK DC280 ZOOM DIGITAL CAMERA_1999-05-31_1200.jpg
Make                            : EASTMAN KODAK COMPANY
Model                           : KODAK DC280 ZOOM DIGITAL CAMERA

You can do this with ExifTool using a regular expression. I use this:

exiftool $TARGET '-filename<${createdate}_${model;s/-//g;s/ //g;tr/A-Z/a-z/}_${filename;tr/A-Z/a-z/}' -d %Y%m%d

which removes dashes and spaces and lower-cases the tag — it's the ${model;s/-//g;s/ //g;tr/A-Z/a-z/} part. You can use basically any perl-compatible regular expression there to do the transformation. If you're not familiar with this, you can read a bit more in the perl docs or on other tutorials online. The specifics of this scripting is out of scope for photography, I think, but this should get you started.
