I am currently working on a project that involve using a HC-SR04 Sonar sensor to control the lights of a Adafruit NeoPixel 24 Leds Ring. Yesterday I quickly designed a 3D model with DesignSpark Mechanical that I am using to center the sensor inside the led ring. I have also added a few spaces where the cable can pass though without disturbing the flat surface.
You can download it from GitHub, and there will probably be updates on the design in a near future.
What do you think?
