3D Printed Wearable Video Goggles

mask-outline
Adjust the overall size of the goggle frame by editing the curves that make it up. Measure your forehead, cheeks and nose to adjust the cylinders that make the cuts into the hood.

shell-mask

Import the .svg paths into your favorite CAD program and extrude the mask 2mm thick. This will provide a sturdy frame for the hood. Make a copy of the mask shape. Select the bottom and top faces and select the shell function to build the frame for the goggles.

merge-mtn

Make a slight bigger copy of the frame, this will act as the monitor and driver board mount. Sandwich and combine the the shelled frame, bigger outline and the original extruded shape.

adjust-lens

Extrude another frame that will house both lenses. Build one lens frame and then use the mirror function to make it symmetrical.

adjust-lens2

Use different lens sizes by increasing / decreasing the inner walls of the lens frame.

adjust-head

Adjust the goggle hood shape by editing each cylinder. The bigger one controls the forehead shape. Measure the depth and width of your head to get a general size for the hood.

adjust-hood

Do the same for your nose and cheeks and adjust the shapes. Build the hood shape by subtracting each cylinder away from the main hood. Test print a short version of the hood to check the fitting on your head.

adjust-mnt

Build the monitor / driver board mount with a cube that is slightly bigger then the over goggle frame. Use the sensor measurements to creature the mounting holes.

measure-board

Use a caliper to measure the mounting holes for our sensor boards. Start with the inner radius of the screw holes and then measure how far apart they are from each other’s center.

build-hole-map

Use the measurements to create the stand offs needed to secure the mounting screws. Combine each stand off together by making a framing structure that connects each stand off.

subtract-screw-holes

Combine the stand offs and framing structures and subtract the cylinders for the screws holes.

top-btm-tray

Easily flip the mounting placement by rotating and using the mirror functions.

vr-hero

Add tabs to connect the monitor mount and hood, holes for elastic straps and screws and fire up some 3D head tracking enabled games!

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!
