I made this Linux Mint logo emblem to cover up the Apple logo on my old MacBook that now runs Linux. I am not sure if it will cover the logo of all MacBooks but i am sure that it can be scaled to needs.

I used Prusa Slicer, to slice it, and it automatically offered the option of a color change. I used a translucent red for the lower part and a dark grey for the top. You may want to experiment a bit with the types and infills to get the appropriate effect. I used very fine layer hight as well as ironing to get a smoother surface.

Then simply glued it on top of the illuminated logo

PS: Many failed attempts went into take this fairly bad picture - i apologize but the dogs were too comfortable
