Shimano EC-E6002 charger lock ring

This print mounts to your Shimano  EC-E6002 charger using two of the original housing screws.
It provides a ring which can be used to lock the charger to a bike using a bike lock or chain enabling you to charge in public places without the charger being stolen.

Print in a material that withstands the outside world.
I added extra outer walls for strength.
