This is a lightweight mod for the baseplate for the Logitech G502. After installing this mod, removing the light diffuser in the mouse, and replacing the scrollwheel with one thats lighter weight and plastic this brings the mouses weight down to around 85 grams.

I suggest using these mouse skates, https://www.amazon.com/Ceramic-mouse-pads-Lexip-PC-Mac/dp/B07MW5XJ8G/ref=sr_1_2_pp?crid=7C2WF4K3FZN4&keywords=lexip+ceramic+mouse+feet&qid=1697333982&sprefix=lexip+mouse+%2Caps%2C139&sr=8-2

simply install them over the screw holes once the mouse is assembled.
