Nautilus Shell Speakers -Finishing 3D Prints

While browsing Thingiverse the other day, I came across this intriguing speaker design based on the famous B & W ‘Nautilus’ speakers. https://www.thingiverse.com/thing:2790097

I decided to make my own set and this is what I came up with:

They will be available on my Etsy very soon: https://www.etsy.com/uk/shop/MakeALittleMore?ref=l2-shopheader-name

And now for a brief description of how I made them:

 

 

This is one of the parts fresh off the printer and the layer lines are very visible. Conveniently the layer steps almost resemble some of the patterning you find on a shell anyway so this will help with the overall aesthetic and saves sanding time.

 

A combination of wood filler:

 

Some sanding and then plastic primer:

 

Resulted in a pair of speaker enclosures looking like this:

As is apparent the layer lines are still visible but reduced marginally. The next step is to coat the speakers in a mock stone paint that adds a 3d texture to the surface to mimic stone:

 

This stone effect finish hides the layer lines and any imperfections not filled during sanding and filling.

 

Next, some elegant speaker spikes were made using m6 long bolts sanded to a point:

Then some oak sleeves were machined on the CNC router:

And then epoxied onto the bolts:

 

Speaker spikes could then be attached.

Next I made an oak spacer for the woofers that added a nice aesthetic to the front of the speaker and complemented the wood on the spikes.

Final assembly was easy although the binding posts were fiddly to install as they are located deep inside the body of the speaker.
