This Outer Shell Mouse design is compatible with the mouse components kit 002.
You can print the bottom shell from Bambu Wireless Mouse 002 https://makerworld.com/en/models/13716#profileId-14573
This is only the top shell. I've used Bambu Marble filament, but in my opinion this is not a good choice for printing thin lines (eg 0.1mm layers).
I have printed with 0.2mm layer, and with Bambu marble, looks better.
I have included also the model with 2 color (skull can be printed with another color, it's not just a cut out in the model). I didn't print this version, as it takes many hours, but feel free to try it. (no profile created for it, just download the file)
