Logitech MX Mechanical keyboard keycap

I made this because the original keycap has only one language, so I tried to print new keycaps with another language. I still don't know how to fill the gap and make the light scattered outside the keycap. The guide fits very well.
I uploaded each part separately so you can configure the design you want. File include:
1- The guide that can be attached to any cap design.
2- The cap itself.
3- A complete keycap.
Update: I printed the keycaps (see the photo) and then added transparent stickers with black ink, so it works fine with white filament and can pass the light underneath.
