3D Printed DIY Volume Controller

This DIY is a volume controller that will insert inside the keyboard. (Developed for Mac only.)From previous videos to now, I've built up from the default device to make one keyboard, so I've made a video so that even DIY beginners can follow it.I also attached "3D model file" + "Arduino source code" below.[Supplies]1.
