Update Aug 2023: Made the Bluetooth/WiFi toggle button more accessible as I found I was switching my Chromecast or Spotify more often then I thought I would. See red-circled picture above.
I bought an Arylic Up2Stream Mini and the DAC upgrade to add modern connectivity to my 1980's amplifier and speakers. I can't be happier with the functionality and the DAC makes a noticeable difference to the audio quality. This board and the DAC upgrade come as bare PCBs so I knew they'd need something to protect them, especially with little ones roaming around. This enclosure is my answer.
I use 3/8" long #4 plastite thread forming screws for assembly, they're absolutely amazing for printed plastic parts.
No supports needed if you orient the pieces as shown.
