Just a simple small shelf for the Apple HomePod mini. The bottom of the HomePod fits into the lowered section keeping the HomePod nicely centered. The wall facing plate has a small raceway for the USB power cable to make it look nice and clean. Also in case the HomePod is pushed off the shelf it is secured by the cable.
To make it look really clean I used "CMC-06" cable raceway (wall cord hider) from Amazon, to run the power cable straight down from the shelf.
