Machine Sewing molded cases?

CDK - Thank you for the picture.  It helps to know what I am looking for.  I found this on ebay - not quite as narrow as yours, but it looks like it could be ground down a little if needed.

The inline foot is obviously worth a look. Using a zipper foot would be my first go to simply because I already have em.They come in right and left flavours. Another approach would be to build the flanges oversize and cut to size after sewing.

Your not going to find an in-line for your Juki compound feed. So just use or buy a narrow zipper like people mentioned above in posts . 441's are easy to find for in-line press-foot. You can also just cut and make your own in-line foot.

If you use a thin zipper press-foot, It really NOT going to matter much for your application . All that matters is if you have a 'full' flat heel on that thin zipper foot for good press contact. 
What I mean with a 'full flat heal' is one that does Not have a radius cut Heel . Your L-foot is mute anyway, and just going to float off the edge, because it not touching the material, and you have open boundaries on the left. The thin zip-foot is reallyNot in the way, and you can just cut it off and leave the Heel if you want and make that foot a in-line .
With an in-line press-foot riding back behind your center feed foot, and getting to those tight looking right radius curves. Your in-line foot is going to swing-off your stitch line and probably not even touch your material until you get around it and back to a straight-line stitch. So when you get to those R-turns. You needing to go slow and use your fingers to press and do a slow walk with the turn with center press-foot.

What you Really NEED to do is trim/cut a nice center foot on the needle-feed, and that lets you walk tighter, and helps give you a nice clean visual. 
I just did one tonight on my 1541 for doing similar to what you asking about. It easy to cut and shape feet. I mostly use just a dremel and a grinder. Just keep dipping in cool water as you go so not to harshly over-heat the steel.

All of the cases i make have a bit of excess around the edge just wide enough for the (441 clone) machine to  sew without changing the foot.  Once sewn, i sand the excess off,then  edge dye, burnish,  etc
