When I upgraded from a minivan to a half-ton pickup truck, I knew I had to do something to make my stock vehicle special. Inspired by a TikTok video, I set about making a mod that few, if anyone else was sporting on their truck.

Supplies

3D Printer (I used a Prusa i3MK3S with MMU2 attachment)

PETG Filament (black, white, and red)

7" googly eyes from Amazon

Two-part Epoxy (I used TotalBoat brand)

Zip Ties

Step 1: Design and Materials

I first acquired the largest googly eyes I could find on Amazon. This was easier than you would imagine, and in short order I had a pair of 7" diameter eyes. I designed the mounts in Autodesk Fusion 360, making it strong enough to survive highway speeds. The tongue is meant to be reminiscent of a dog happily hanging its head out the window of a moving car.

Step 2: Printing

The parts were all printed on a Prusa i3MK3S printer, taking advantage of the Multi Materials Unit (MMU2) for the multiple colors of the mouth and tongue. Print files and details can be found here .

Step 3: Assembly

The attachment points press-fit into the holes in the mounts, and can be CA glued for extra security. The eyes and mouth/tongue are glued into the mounts using a generous amount of two-part epoxy.
