ND filter mount for Xiaomi Yi Action Camera

thingiverse

This is a custom filter holder designed specifically for the Xiaomi Yi action camera. Using thin plastic clips from sunglasses, I mounted this holder onto the camera using a sturdy mount that provides a secure fit. To capture smooth footage of flights with an FPV drone, I needed to add a neutral density (ND) filter to the camera's lens. Unfortunately, ND filters are only available for SJCam and GoPro cameras, so I opted to create my own. The design features a tight-fitting frame that is slightly thicker on the sides, ensuring it stays securely attached to the camera during flight operations. To print this holder, use TPU material with the flange facing downwards, eliminating the need for supports or bridging.
