In this project, we’re making a Face Mask inspired by Starro from The Suicide Squad.

This mask is flexible and features blue and purples to look like those creepy starfish face huggers.

The HalloWing is the perfect board for this type of project! 

It’s an easy way to get an animation eyeball with no coding skills required.

Construction

The mask is 3d printed in flexible filament so it can wrap around your face. 

It’s made from two separate pieces that are fastened together with machine screws. 

All you need for this project is the HalloWing, a small LiPoly battery and a convex lens.

The mask is 3D printed in Ninjaflex. This filament features a shore hardness of 85A and it’s both flexible and elastic.

The flap on the back allows access to the built-in power switch so it’s easy to turn on and off.

Rechargeable

 

Easily power up Starro! The HalloWing includes a LiPoly battery port with built in recharging capability! 

Simply plug it via USB cable into a USB port to recharge the battery plugged into the JST port! While charging, the orange LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy!

Parts

Components are housed inside Starro's body.

The lens press-fits into the lid in the center of the body.

Build-in standoffs help to securely mount the HalloWing to the upper half of the body.

JST extension cable can safely route the battery to a pocket.

Clean Up

 

These parts are stringy and need a bit of cleanup which is easy to do with a pair of flush snips.

 

Spray Paint

 

To color the parts, you can airbrush both sides starting with some shades of purple.

Then you can add some blue and blend them together to make some gradients.

Airbrushing Ninjaflex is better than acrylic paints because it won’t crack when flexing.



Attach Lens

 

The lens is added to the center hole cutout and is held in place with the lip along the edge.

The HalloWing board is placed on top with the mounting holes lined up. 

 

Screws

 

Machine screws can then be fastened to the built-in standoffs for a nice and secured fit.

The placement of the board is set up so the display is exactly in the center of the mask.

Align Parts

 

The back side can then be added with the flap lined up with the built-in switch.

Machine screws are added to each of the mounting tabs with the two sides held together.

Paint Screws

 

Use acrylic paint on the screws to help them blend into the body.

 

JST Extension Cable

 

You can add an extension cable for a bigger battery and hide it in your pocket so it’s not directly over your face.

Mold arms

 

The tips of the mask are bent and held in place overnight so it’ll retain a curved shape.

 

Head Strap

 

You can add a strap or a piece of Ninjaflex to act as a string to keep the mask fitted over your face.

We hope this inspires you to try out some Ninjaflex and check out the Adafruit HalloWing for your next project!
