XiaoYi 4K Camera Accessories
The Yi Technology - 4K Action Camera (Aliexpress or Amazon US or Amazon DE) is a pretty nice device. In order to mount it to my electric scooter I designed a holder.
Models are here on Onshape (plus a lens cover)
Later I learned that on parts that are under mechanical stress it is worth to think twice how to print them. Thankfully the camera survived including the video it was recording.
