25th Anniversary Gift for Carol – A 3D Printed Silver Narwhal


This is the story of my 25th Anniversary gift to my wife, Carol Hobbs. This is the story of how it came to be, and why.



In the winter of 1978 several whales became trapped under the ice in Hall’s Bay, Newfoundland, on which lies my hometown of Springdale. Several humpbacks and a rare Narwhal. Rare, because they are high arctic whales, and rarely get this far south.

Throughout the winter, locals kept a large hole open so the whales could breathe. In the spring, an ice-breaker came in to the bay close enough to the hole that the whales could escape. Not all of them survived the winter. The belief is that mid-winter, one made a run for it, but Hall’s Bay, while being very deep, is also very long, and one humpback was found dead. The rest, though, we believe survived. They were gone the day after the ice was opened up.

“Springy”, as some of the locals called this young Narwhal, whose tusk was not yet fully formed.

One one particularly nice day, Carol skated out on the perfectly smooth ice, and spent some time with the whales. It was amazing. My friends and I skated out there as well on a different day. Here we were, mere feet from the edge of this twenty-foot-diameter hole, and these whales kept coming up and getting air. The big humpbacks made a show of it, but the little Narwhal would kind of surface quietly, we’d get a glimpse of her, and then she’d dip silently down into the water again.

Carol wrote a poem about the experience, which has been published multiple times, and is one of my favorite poems of her large body of work. The poem was called “Narwhal”.


Hall’s Bay is a china plate.
I skate far out to the breathing hole
where the men chop the ice away.
The echo of auger and axe
grapples the lip of hills.
They are building a lung for whales –
a pair of humpbacks, a narwhal
surfacing through the slush.
The little narwhal lingers,
mottled back steaming.
Its eye oily in the dark cup,
me mirrored in the eye-slick,
the horn spiraling into brittle air.

-Carol Hobbs

On her birthday in 2010, I gave her this installation, which hangs on our wall in our new house, at the base of the stair under a tall window. (Seen here in our apartment previously)


I framed a copy of her poem, with a print of Springy the whale. Under it is a shelf with brass brackets holding about 18 inches of a narwhal horn. Not a real one of course. That would be priceless. This is a casting in dental polymer of a real one, one of a rare few that someone was lucky enough to get a full casting of. (They also make available a 5 foot version.)


The Silver Narwhal

Last year, after our 24th Anniversary, I realized that the next one would be the big 25. Silver. I began thinking almost immediately what to get Carol for our 25th Anniversary that was silver.

At the time I had printed some things at Shapeways, an online 3D printing service. They keep adding materials and services, and at some point they introduced 3D printing in precious metals. They print the item in wax, then use the centuries-old lost-wax casting process in whatever metal you like, including solid gold and platinum.

So this was perfect. I would create a silver narwhal for her.

As time was getting on mid-year and I found myself with little time for 3D modeling and printing, I searched the web for models that would suit. I found a whale model that was very similar to a narwhal (without the horn) and downloaded that.

I found a splash model (as part of something else) and separated out the water splash.

I created the base myself (a simple oval, with an indented bottom, and an inscription.)

I smoothed out the whale, because I thought that in the Shapeways preview software that the facets of the original model would be noticeable in metal, and posed the whale in the water base I had created, using a boolean subtract to remove the bottom of the whale.

Here is a test print I did on my own printer.


The horn is a simple standard toothpick. It works!

I then cut some interior space out (waste of silver) and sent it away to Shapeways for a silver print. I had the option of raw or polished. I felt the whale should be polished, shining as if coming up from the ocean, covered in water.

This wasn’t cheap, and I was nervous at how it would turn out, being my first metal print.

Then it arrived:


In a nice, soft microfiber bag to keep it safe.

And then I opened it:



I couldn’t believe how it turned out. It was perfect!

Emboldened with confidence, I sent for the base to be printed in raw bronze. I opted not to have it polished. Two polished metals in the same piece would be harder to see. The two shiny metals would compete with each other for attention.

I forgot to photograph the base separate, but it turned out very nicely. I was worried because a portion of the wave was suspended above the water, very thin, splashing out past the base itself, and my own printer had issue with that. Shapeways printing, however, did not. It was great.

Here is the base’s bottom, with inscription:


So I used a binary clear epoxy to bind the pieces together:


Then I used my Dremel to carve a spiral into the toothpick, then stained it with the same stain we have on our front porch, which Carol and I put down this summer.

I varnished it, and used binary epoxy to attach the horn.


The Presentation

How best to present this? I thought it should come in a box, like a piece of jewelry, but not have her expect jewelry. A cubic box I found at Michael’s Craft Store would do the trick:


This one has a magnetic clasp, and a deep interior:



So I stained this box in the same stain we have on our back deck, which Charlotte, Carol and I did early in the summer:


And a few coats of semi-gloss satin varnish.narwhal-box-04

But that couldn’t be all. I had to have something inside to hold the piece. Most jewelry boxes have a velvet covered sponge insert. I knew it had to be an insert, and it had to hold the piece firmly in place.

So I used my own 3D printer to create an insert that had a perfect inset for the base: A quick test print for fit:

narwhal-base-test-print-01 narwhal-base-test-print-02

And then I printed the full insert, much thicker.

And then what? I had decided to cover it with some kind of fabric, and I had only to decide what. I found this nice watery blue batique at Michael’s, and cut it to shape and wrapped it around my insert:


I used a spray adhesive, and an elastic to keep it in place while it dried.

Then I used a plastic version of the base and a clamp to push the fabric into the aperture I had cut:


Testing it with the final piece showed it would work perfectly:


But it would still flop around the box, (which would not be good, and might, indeed, break the wooden horn.)

So I 3D printed another part that would fit inside the cover of the box and hold the whale down while the box was closed:


I used an oval cylindrical shape, and then used the actual whale model (in 3D) to cut out a part of it that would ensure it fit down exactly over the whale’s back and clamp it down while the box lid was closed. It could go nowhere:


Used contact cement to glue these inserts firmly into the box. I used a stand-in piece in place of the metal final work, and held the box closed with a clamp while the inserts dried in place:


And this is what it looked like when finished:


But that was not all. I needed a finishing piece: A silver engraved plaque. I went to Things Engraved in our local mall and got the perfect oval silver plate and had engraved on it: “For Carol On Our 25th Anniversary, Love, Sean”


And that’s the complete package.

I gave it to her on our anniversary and she loved it.

  1. Wow what a love story, you sure put a lot of thought and hard work into this gift, Cogtatulations on being married 25 years, hope you have many more.

  2. Sean, this is a beautiful story and a great job!!! I remember very well when the whales were trapped in Hall’s Bay!!!

  3. Such a interesting story that shows your love and commitment to your wife. Beautiful work on the “special” piece. Congrats to the both of you on your 25th Anniversary!

  4. Hello, how are you? I’m Brazilian and I was looking at your site, would you have the files or the narwhal links that you made for your wife? I would like to use it for a game of rpg

    • Sorry. This is fully intended as a one-off piece of art for my wife. I won’t be making copies available. However, if you search Thingiverse for whales, I’m sure you can come up with something quite suitable. There is also the splash of water. These can easily be adapted for your use.
