I have this little sylvania netbook and when I got it, it was missing the tab key, one of the number keys, and the tilde key. So I made them using freecad while learning to use freecad. If you need other keys, just tell me and Ill post up files for other keys.

I just super glued them to the rubber parts that make up the keyboard, and they work fine. They look almost identical to the other keys that were already on there.

They need to be enlarged by 10x to be the right size (my bad, measured in cm, and did freecad drawing in mm), but print them out, paint them or use black filament, and glue them on.

This is to fix the tab/shift keys, any of the number keys or letter keys, and the tilde/other tiny keys at the far right of the keyboard.
