Update 13 Sep 2023: Some minor changes to improve the flexibility of the catch. Removed earlier version.
Created this because I added a DC supply mod to the Mi Scale 2 that requires cutting a hole in the battery cover for the wire to pass through. I will elaborate in another design post.
Does not work as well as the original, good enough for me. Supports are required only at the latches.
The author marked this model as their own original creation.
