Rover 75 front bumper rubber ring

Front bumper bolts with rubber ring (Part number DYG100650) for Rover 75 1999-2002 is no longer available. I drew the ring in Tinkercad. I printed it in PLE (Ninjatek Chinchilla) in the original dimensions. It is very close to the original part. The ring has to be printed at bit larger to fit the bolt, if a less flexible material is used.

I shotblasted, zinck plated and painted the bolts.
