Finger Shark

3D model description

Shark Tank? Shark Week? Sharknado? Pfah.

Finger Shark.

If you've ever done a 3D printing demo you've seen a dozen kids get all excited about the technology, watched your printer struggle to burp out a Yoda before the event ends, and then seen dejected kids walk away empty-handed.

(A brief note to folks who do 3D printing demos: as of August 2014 there are more 3D printed Yodas in the world than there are children, so you can stop printing them now.)

Never again, my friends. Finger Shark is fun, fashionable, and fabricates fast. Print a dozen to chum the waters at your next Maker event.

Finger Shark is designed for a size 7 ring, which should snugly fit the fingers of most adults.

You'll need to scale all three parts of Finger Shark to fit smaller fingers. To that end, the handy-dandy Zheng3 Ring Sizing PDF ( will let you teach a little basic algebra while the kids are printing finger sharks.

(Another brief note to folks who do 3D printing demos: attempting to teach algebra during a demo may cause kids to shy away from your booth.)


Seej patient zero. Barbie Armor Designer, artist, worst programmer ever. Mostly illiterate, but has minimal competence in spoken Mandarin. Not real clear on Ohm's law.
