I have a rear bike light with an integrated camera and found that in muddy conditions, mud got kicked up from the rear tyre and covered the camera, meaning in the event of an incident, it would be useless as it wouldn't capture the crash. I designed and printed this mudguard to stop this from happening. I printed it I a 'transparent' filament so the lights can still be seen from the side of the bike, which wouldn't be possible with an opaque filament
I scaled the object down to 98% to ensure a nice tight fit. The normal scale was too loose
