Logitech G304 G305 Mouse Scroll Wheel Outer Ring ~ Aging Replacement

Background:

Logitech mouse G304 / G305, after long-term use, the rubber on the outer circle of the scroll wheel ages, blocking the bracket, resulting in the wheel rolling unsmoothly or even not being able to be pushed

Replace the aged rubber with a printed outer circle made of a hard material to solve the problem.

During the fine-tuning of the model, we also need to address:

1. Smooth disassembly and assembly of the outer circle and inner core, not too tight or too loose
   
   

2. The outer circle thickness is greater than the inner core thickness, so the middle finger feels comfortable when clicking the scroll wheel

   

   
   

3. The tooth spacing is appropriate, the rolling is smooth, not tiring, nor does it slip
   
   
   
4. Try to achieve the maximum outer circle diameter, put it into the wheel bracket, and fill the reserved space. The new wheel is more protruding than the original wheel, which is easier to operate
   
   

It took several versions to finalize these fine-tuning adjustments
