This is the alternative bezel for Panasonic MSX2 FS-A1F SLIM-FDD kit designed/produced by Lost Technology, this kit enables FDD replacement from genuine 3.5inch version to SLIM-FDD used for Wrap-top/Note PC.
NOTE: It is not guaranteed for every type of SLIM-FDD. And this is still version 0.1 stl model, the bezel model also has some room to improve fittability/stability.
SLIM-FDD kit (PCB parts only, need to figure fittable SLIM-FDD out by yourself, the site description is Japanese only) :
