I have had to fix my mouse "double clicking" a few times before. For mechanical mice it is a relatively simple repair that has good tutorials on youtube already. The repair requires you to open the mouse, open the mechanical switch, and re-bend the spring. Simple! Well I have done this 3 times now and the white button on the left switch was greatly worn down.
Here I present a file for a new switch component!
It may require some sanding to make sure it is smooth, but my mouse is good for a few more years of abuse in only a few minutes!
Thanks I hope this helps. If you have any questions feel free to ask.
