Pen-Plug for Vodafone/Huawei 845/u8100

thingiverse

This pen is for the Vodafone 845 (Huawei v845/u8100), which connects to the audio jack and coils around its edge. Although functional, it requires further fine-tuning of the curve. I no longer use it due to issues with the 3.5mm plug being mistaken for a microphone by the phone. The USB option seemed more delicate; however, you might adapt this design idea for geocaching or protecting your device's ports. Remember to adjust the curvature and print according to your printer's orientation.
