the additions fits not this well

Hi,
I have printed your remix, thanks for this. But some question is still available... How is the speaker grille mounted or how does it stay i place?
Thanks you very much for the remixes!
Have you gotten yours working?
I've gotten mine all soldered up, flashed with the code example on the blog post- I can toggle the lights via ESPHome but unable to talk to the thing. Can't tell if the mic or speaker works, wondering if you had any other issues with this build... Hass has the voice assistant enabled with piper and whisper enabled/paired. Also tried an older version of esp firmware. Devices shows nominal in the logs. Thoughts?
