In 2021 I was lucky, I buy a Moto Guzzi Griso SE Tenni, one of the last Moto Guzzi develop with Aprilia before Piaggio bought both.
Unfortunately the motorbike in past years get terrible maintenance service. So I roll up my sleeves and repair what they done.
Some of the breakdown was clutch sensor, some damages screws and the rubber on left lights switch AP8127703. I have looking on web to find this rubber button, but all I was able to find was the full lights switch (realy expansive solution with no warranty). So I decided to make the rubber on my own.
After disassembled and removed the rubber button I measured it to realize a injection mold.
With a CNC I get the three pieces of aluminum injection mold.
In the picture you can see a pink rubber for test it. Since it worked I made it with black rubber and now you can't notice difference from the old AP8127703 rubber button and my.
