This is an adaptation ofSgt. Davis's zero-rat modification, suitable for Logitech G102/203, originally inspired byOptimumtechIf your G102/203 is a second-generation LIGHTSYNC version, DavisSgt's model will not be applicable. You can verify this by checking the product number

This adaptation aims to solve the compatibility issue

Attention- I can't guarantee compatibility with the G102/203 Prodigy or the first-generation LIGHTSYNC, as I don't own these models. Please use them at your own risk.

You will use the original screws on the mouse case to fix the PCB to the model, in the same position as on the original case. The two mouse buttons are fixed using screws underneath the mouse feet

I've also included two optional components that make it easier to press the DPI button. You can choose one with an extended cover on the back to slightly diffuse the RGB lighting.g102_dpiDiffuse.stl)，or just one of the buttonsg102_dpi.stl)

Printing Notes:

• Tested by the People's Liberation Army of China
• It has passed the layer height test of 0.16mm, but 0.20mm should also be feasible
• Do you need support? - Yes, I do.g102_btn.stlUse a tree-like support in the suspended cutout area where the rollers are located.
