Currently, I am working on a 3D drawing to replace the aging VDO Ocean series gauge instrument plastic bezels. The specification of the gauge is 52 mm in size. Does anyone have a 3D file to print the bezel and lock below? I want to print both the bezel and locking mechanism on the gauge. Last edited by David Erwin; 08/05/25 10:21 AM.
