Gone Fishin'


December 24, 2017



This year, I bought my parents a 3D printer as an early Christmas gift. The first thing my dad asked me when he saw it was "Can you make fishing lures with that thing..?"

We thought it was worth a shot.





To my direct family, I'm known as a bigtime collector of Heddon River Runt fishing lures. I started my collection around age six, and today it sits at a little over a dozen lures total.

"FOR DISPLAY ONLY !" ...a provisionary sign meant to ward off trade-hungry collectors


It's obvious I have a soft spot for the goofy little things, so when the topic of 3D printed fishing lures came up, making a River Runt felt like a logical first step.


Digital Reconstruction


Now, we didn't want to make something like a River Runt - we wanted to make the real deal. To get our lure as close as possible to the original, we set up a Blender scene with front, side, and top reference images, then traced them to-scale in 3D.



Next, we added screw holes and a hollow cavity to increase buoyancy.



Sure that our modeling work was behind us, we fired up our shiny new Monoprice Select Mini and kicked back.


Screwed Up


D'oh! We forgot to add tolerances to our screw holes. After snapping a couple brass screw heads and getting creative with a drill bit, we decided to go back to the drawing board and loosen things up a little.

Right: Buoyancy testing was conducted in our state-of-the-art artificial pond


A few clicks in Blender (and about an hour to print another lure) and we would have our second prototype - this time a winner.


Some Assembly Required


While our second prototype printed, we set out to buy supplies. We picked up screws at Home Depot and hooks and adhesive-backed eyes at WalMart. Hook hangers were sourced from a "junker" lure, and a brass lip was hand-crafted from a 270 WSM bullet casing using a dremel tool and hand files.

Left: That's probably safe...
Right: "Don't give me no lip"

Right: Finishing touches



Bioluminescence


Did I mention this thing glows in the dark? We used Hatchbox's Green Glow in the Dark PLA for this project, and the stuff REALLY glows.

I'm definitely attracted to glow in the dark stuff - maybe fish are too.
Angler fish do pretty well for themselves, right?


Now that's all well and good, but, you're asking, does it catch fish..?


You Bet it Does




Left: Not bad for a first catch
Right: We accidentally ( ! ) caught another fish while trying to record video of the lure's action in water


To say the thing catches fish is an understatement. After about 30 minutes of fishing, we caught so many that we got tired of taking pictures.

To say we grew attached to the thing would also be an understatement. We decided to retire it pretty early on for fear of losing it to the depths - keeping in mind that if we wanted to, we could always print another one to actually use :^)

















If You Teach a Man to Fish Print...


It's safe to say my dad caught the 3D printing bug.
After I left he ended up designing and printing several more lures of his own.

It's worth mentioning that none of the lures we printed are in production anymore. The Heddon River Runt, for example, was introduced in 1933 and went out of production in the mid 1980's(1).
In good condition and in a "rare" color, some of these vintage lures (like the Heddon Punkin Seed) will sell for well over a hundred dollars on auction sites like eBay, which, in my opinion, makes them kind of too valuable to fish with. Using these reproductions was my first experience fishing on most of these old-timey designs.




So What's Next?


Now that we've "gotten our feet wet" making reproduction lures, we plan on printing and testing some of our own original designs.

Stay tuned !
