I made some edits to the original Moto G7 power case made by 3D_Printing_Innovations adding things like:

• Some slits near the bottom to make it easier to put the case on and take it off without cracking the case.
• I made the headphone port larger to accommodate headphones with larger plugs.

The included zip file also includes the .blend file that I made my edits on. Feel free to make your own edits and personalizations. Blender 2.8.2 was used
