This is a remix of DavisSgt's zerømouse mod for the Logitech G102/203, which was initially inspired by optimumtech. DavisSgt's model will not fit if your G102/203 is the 2ⁿᵈ generation LIGHTSYNC version. You can verify by checking the sticker on the underside of your mouse for the product number (P/N: 810-008818).

This remix serves to address the fitment issue.

NOTE - I cannot guarantee compatibility with G102/203 Prodigy or 1ˢᵗ generation LIGHTSYNC since I do not own those. Attempt at your own risk.

You will be using the stock screws from the mouse shell to secure the PCB to the model, in the same places as they were on the original shell. The two mouse buttons are secured using the screws that were underneath the mouse feet.

I have also included two optional parts that make it easier to press the DPI button. You can choose between the one that has an extended cover at the back to diffuse the RGB slightly (g102_dpiDiffuse.stl), or the one that's just the button (g102_dpi.stl).

Print notes:

• Tested with PLA
• Tested with 0.16mm layer height, but 0.20mm should be fine
• Supports needed? - Yes, use tree supports for g102_btn.stl, at the suspended cutout area where the scroll-wheel goes
