Apeman Action Cams and perhaps other Apeman cams have a lens that extend beyond their bezel and as such are very susceptible lens coat scratching. A ring to fits over the bezel and extends beyond the lens can mitigate accidental scratching. The build has a small wall thickness to allow a camera with this ring to fit inside the Apeman waterproof case.

This design is proofed on A80 and A87 cameras.

ABS print

The thickness of the design requires careful separation from raft or rim.
Before removal I painted the print with acetone being careful not to penetrate to the area of separation. Once separated, a second coating of acetone is applied to to the outside and ends. The acetone promotes layer integrity.

The rings press on in a tight fit over the Apeman lens bezel.

Different model Apeman cameras have different lens diopters. The 6.5 mm height of this design protects the smallest diopter Apeman lenses I have experienced and while not interfering with installation in the camera's waterproof container.
