Nautilus Speakers

Remixed from the basic shape, added legs holes, designed some legs, and added power and audio connector holes.

A RaspberryPi inside with a DAC hat, running Raspotify turned them into a Spotify Connect device. Can be controlled directly from Spotify on my phone, or via Alexa voice commands. The cones are £20 40Watt Full-range woofers.

Two halves printed without supports in standard black PLA with some plastic putty filler in the cracks. Some white primer, then the much-better-than-expected granite effect spray paint.

The legs and trim are in Woodfil PLA (which is fantastic), with a bit of Wood Stain on top. Some £5 metal spikes finish it off.

Turned out way better than I expected, both in looks and sound quality :)
