As promised here’s an SVG file for a Google Home Mini holder with a single-screw “keyhole” mounting scheme…
I made the first one out of PG 1/8" medium draftboard. The ~0.7 mm thinner PG medium clear acrylic version shown above has arms that are definitely not a “press-fit” into the base—but with some liberal use of acrylic glue you can get a strong, stable mount.
It took a few iterations of the “arms” to precisely match the compound curves of the Google device’s profile. Anyone have any suggestions for getting something like that into Inkscape? I started with a photo of the device on edge, but that was way off.
@JeremyNielsen showed us his version, which I like too. I’m not exactly sure how difficult his is to mount? My version makes it easy to clink the Google Home Mini in/out after installing the holder on a wall or ceiling.
Time to print some more! If I told you how many digital voice assistants we have here, you’d all laugh—so I won’t!
