This is a holder for the Google Home Mini that fits into a car cup holder and provides a safe way to hold the Mini for in-car use! Note that you will need an in-car wifi to use the Home Mini.
See my other make for the Amazon Echo Dot which works well enough in the car for music via Spotify but the Echo it is not very good for podcasts. This is because the dot does not remember where you listened to so if your trip is shorter than the podcast then you have to start from the beginning of the podcast every time. To compound the problem, there is no "skip x seconds" to quickly get to the point you left off. The good news is that the Google podcast player does remember where you got to AND it also supports skipping x seconds so it is a much better podcast experience.
The problem the Google Home Mini has is that it does not have an AUX out to connect to the car speaker. Not all cars allow bluetooth pairing allowing the car speakers to play the media from the Mini. The solution seems to be to install a Google Chromecast Audio in the car as well and plug it into the AUX in on the car. If you set it up the default cast device in the Google home Mini settings then it seems to work quite well.
This make is based roughly on my earlier Amazon Dot design but the top is heavily modified to hold the Google Home Mini whilst still allowing the USB connector and switch to be accessed.
The design is in two parts - the cup and the carrier and both need to be glued together using superglue. You will see there are two guide channels in the underside of the top carrier part. This is to allow the cup to mounted in a central position or in an offset position depending on the space available around your cup holders. Check before you glue them together. The Google Home Mini stays in the carrier by gravity but you might put some double sided tape at the bottom if more grip is needed.
I have uploaded the STL files and the openscad for the cup in case you need to make it shorter or taller to fit your car.
I recommend printing this with Inova1800, ABS or another higher temperature filament because it can get hot in a car and you don't want this melting in the summer sunshine.
Please like my design if you like it.

After printing - preparing to glue
If your initial payer is too squished when printing the carrier part (that holds the Mini) then the guide channels for the cup will be too narrow. If this happens then you will need to use a file to make them wider.
If you print with support then you will notice two small spots of support in the guide channel in the base of the carrier. These will also need to be removed or they will stop the cup from seating in the channels properly.
Glue with plenty of superglue.
