G305 Featherweight - Logitech G305 Mod

Logitech G304 / G305 Lightweight Mod Kit

Open-frame performance shell engineered for structural rigidity with reduced mass. Designed around the original model of the lightweight shell design of this mouse without making the mouse much heavier. 

Core Features

• Open case architecture
  Ventilated skeletal body for significant weight reduction and improved thermal dissipation. Maintains mounting compatibility with stock PCB and sensor assembly.
• Added Dual-side button support
  Retains both left side button positions. Suitable for left-handed configurations without functional compromise.
• Added 300mAh rechargeable battery
  Replaces the stock AA cell or the AAA cell mod with an integrated lithium rechargeable pack. Lower weight, improved balance, reduced inertia.
• Added USB-C charging interface
  Direct onboard USB-C charging port. Eliminates battery swapping. Clean internal routing with secure strain management.
• PTFE mouse feet included
  Low-friction, high-purity PTFE skates for consistent glide and surface control.
• Added Dedicated PTFE mounting zones
  Engineered recesses ensure precise skate thickness alignment. Prevents lift-off distance inconsistencies and avoids sensor misreading caused by uneven base contact.

Result

Improved balance distribution, lower rotational inertia, consistent sensor tracking, and modernized power architecture—without sacrificing full button functionality.
