Pen-Plug for Vodafone/Huawei 845/u8100

This is a simple pen for the Vodafone 845 (Huawei v845/u8100) that plugs into the auido jack and curls around the edge.
It is not finished but worked, the curve needs a little more adjustment.

I do not use it anymore as the 3.5 audio plug caused problems (Caller did not hear me as the phone expected a microphone).

I did not want to use the USB plug instead as it looked more fragile. But you may can use this as a basic concept (for geocaching dirt protection or another phone)
