This design is comprised of two separate pieces that can be glued together with a few drops of CA glue.
Both can be printed fine without supports in PLA.
The holder clip is universal and will fit your Home Assistant Voice PE without removing its rubber feet, while being almost invisible as it only holds it on its four corners.
The second piece is a flat socket cover with an opening to pass power and audio cables, and this is not universal, it depends on the manufacturer (or even on the model) of your wall sockets. Mine is for the Schneider Electric D-Life family (acting as a replacement of the part MTN4075-6035). You might need to adjust this one to fix your wall socket.
The setup is so minimal and flushed to the wall that it even requires right-angle usb and jack connectors. I used these:

- Angled Aux cable: https://www.aliexpress.com/item/1005006163202905.html
At the end of the cables I have a 2.1 amplifier (2x50w + 100w) ZK-MT21 (https://www.aliexpress.com/item/1005006573639261.html) hidden in the ceiling that powers a pair of 50w ceiling speakers for a very nice sounding experience.
