I just tried this with the TEAX09C005-8 exciter, but I have a few comments:
1) The model is difficult to print on a FDM printer. I have had some marginal luck printing it upside down (finger side down).
I cropped off the bottom 1mm so there is better contact with the bed, and then printed with supports under the finger part.
This leaves a rough surface for the finger, but seems to give dimensionally accurate results where it matters (where the exciter needs to fit):

By recessing into the bed by 1mm, at least the first layer prints with good adhesion:

I had a much better finger surface when printed vertically, but it requires supports for the top surface, which prints imperfectly, and also I had trouble fitting the lid due to elephant's foot on the bottom surface (but maybe that's my own calibration issue):

This seems like a good candidate for a non-planar slicer, but I haven't figured out how to do that. Or maybe I need to find a resin or SDS printer.
2) It would be nice if the spacers/ribs were merged into the housing. (Although on my test fit, the contacter pin is recessed below the surface by several millimeters. I would prefer is the spacers/ribs were as short as possible, and then I can just trim the contacter pins to length if they're too long.
3) Seems like the small circular cutouts near the lid aren't necessary? Or is that for cable routing?
