iPad 9th gen sound booster

After seeing some sound boosters for iPads I decided to try and design my own.
The .stl file has an improvement for a better access to the Home button.
Obs.: My iPad has a thick screen protector I accounted for during the desing (8mm, instead of 7.5mm as indicated in the official measures). If yours get a little loose, a piece of masking tape may solve the issue.
