raspberry pi 5 snap case remix

Remix of model user @pyro uploaded. Added a removable top that can be lifted up just like the official case also added more vents to the bottom as well as a power button to put into the hole based on the design of the v3 case so you should be able to mix and match the parts of the case v2 case has holes and a lip ond the lid so it should stop sliding around(note i don't own a 3d printer so i cant recommend any printer settings).
