Overview
Wearable Frame
3D print a pair of frames for your Adafruit LED Glasses. Designed to fit any
Feather compatible board! Use a STEMMA QT cable to easily connect to an
Adafruit Feather.
3D Printed
The parts are secured using hardware screws and nuts. The frames feature
built-in nose pads for comfort and a better fit. The arms are attached to the
frame built-in hinges using hardware screws and nuts.
LED Glasses Driver nRF52840
This particular arm is designed for the LED Glasses driver board featuring the
nRF52840. Use M2 x 8mm long screws and hex nuts to secure to the 3d printed
arm.
Feather-Compatible
The left-arm features mounting holes sized for any Feather-compatible board
like the Feather RP2040. Use a USB-C cable and a 5V battery pack for
portability.

- 60c heated bed
CAD Assembly
The Feather is secured to the arm with M2.5 x 6mm screws and hex nuts. The two
arms are secured to the frame with M2.5 x 14mm-long machine screws and hex
nuts. The frame is secured to the LED glasses PCB with M3 x 6mm long screws
and hex nuts. The Feather connects to the LED glasses using a 50mm STEMMA QT
cable.
Design Source Files
The project assembly was designed in Fusion 360. This can be downloaded in
different formats like STEP, STL, and more. Electronic components like
Adafruit’s board, displays, connectors, and more can be downloaded from the
