Eachine Trashcan Adapter to use 1S

This is a simple and lightweight adapter to use 1S 250mah/300mah on the original Eachine trashcan battery support, this locks into the space and it's handy to use and super light (less than 1g).
Recommend to print in TPU.

Added new version with more lock than v1.
