Quick & dirty remix to use this part on the original Xiaomi Yi 4k. Obviously doesn't provide much protection for the body of the camera, but at least the lens gets a modicum of cover.
I narrowed the lens hole by 0.25mm for a more snug fit & extended it forward for decent protection for the lens without having to attach glass/perspex in front. I made this for filming at 2.7k/wide with distortion correction active, but not for 4k/wide (it will show in the corners of the footage at 4k/wide).
Printed fine in ABS without raft or enclosure, being careful to keep the room warm & prevent any drafts by opening/closing the door too quickly.
