Threw together a Wyoming Satellite using the Slacker Labs tutorial. It works just fine, but the components do not fit in case he referenced, so I designed my own. The Pi screws into the base with M2.5 screws. The hat is just supported by the 40 pin connector. The two M3 cover screws also hold down the speaker.
The grill is just infill. It was created using a cylindrical modifier in Prusaslicer, with infill set to 25%, zigzag, and no top or bottom layers.
The author marked this model as their own original creation.
