Unsupported hole in battery cover

[stephandobri]

The hole for the screw in the battery cover is unsupported and requires supports to print well.

The standard unsupported hole geometry should be added to the hole.

I've made the changes to the CAD and pushed a new STL, Fusion, and STEP files to the v1.1.3 branch. Looking to include a few more changes before pushing this to main.
