Simple cover for a battery compartment. The length of the single holder pin is a bit short for my case, but it works nevertheless. Dimensions fit for a 2 AA case, but can be freely adjusted.

The holders don't have a lot of support and contact with the big plate, but it works fine for my application and they are surprisingly difficult to break off. YMMV

The code isn't pretty, but it works. Feel free to clean it up and submit a remix.
