We had trouble keeping the Kandao QooCam 8K Enterprise's lenses free from scratches, so this case was designed to keep them covered when not in use.
Keep in mind this case makes contact with the lenses, so you will need to print it with a non-abrasive material. We use Ninjaflex, but you can use something else as long as it has a comparable durometer on the Shore A Hardness Scale (<90A).
Use a lens cloth to clean the lenses whenever you put the cover on or take it off, and the case will keep them safe : )
Nozzle: 0.8mm
Filament: Ninjatek Ninjaflex
