Echo Dot Acoustic Case with Breakaway Supports

Based on: https://www.thingiverse.com/thing:2086867

The original model required supports only in the plug opening - but not all slicers support adding supports in specific areas only (aka Cura).

The only change made to the model was to add 4 small supports to the model inside the plug opening. These break away fairly easily but will need to be filed down just a bit after breaking away.
