Nắp che ống kính Flex Lens Cover

The lens cap can be scaled in your slicer to fit virtually any lens size. Simply measure the outer diameter of your lens barrel in millimeters, then scale the model's X and Y axes uniformly until the inner diameter of the cap matches your measurement and add 1–2mm for a comfortable press-fit. The flexibility of TPU means it will stretch slightly to grip the barrel securely without being difficult to remove.

The inside is lipped for a tighter seal.  Textured outer ring for better drop protection.
