I 3D-Printed a Foxtail-Proof Helmet for My Dog

After a foxtail weed sent his dog Hildegard to the emergency vet, Amos Dudley designed a custom protective helmet. Using an iPhone 3D scan and CAD software, he printed a shell with replaceable mesh inserts for ears and nose, plus a clear lens. The helmet fits well and works as a GoPro mount, but other dogs find it threatening, so it's reserved for hikes.

Who knew dogs move so fast?

    > foxtail grass

    ah yeah we call this spear grass locally (and probably also foxtail) and never read what it can do. (spoiler below)

    they can burrow their way into the bloodstream and travel down to the heart & lungs. So incredibly dangerous for something so pervasive and normal.

    Super cool writeup! The helmet cam at the end was gravy.
