It is a simple replacement for a charger cover of IDEENWELT Hair Clipper but it will probably work for any other charger with the same circuit board size. If you need to modify it to fit your circuit board I added STEP files.

ASSEMBLY:

The assembly is straightfroward, if you wonder what does the little cube does it blocks the movement of the plug-in bolts when you outer plug it in or pull the plug out. It is additionally secured by M2 screws.
