3D Printed Seatbelt Holder for Triumph

I have an old English car, nearly 40 for years old as it happens. While many parts are available new from specialist suppliers, some things are impossible to get hold of.  The costs of remaking the tooling is just prohibitive for the small quantities likely to sell.

There is a nice system to fix the seatbelts in the car when they are not being used. I think this makes the car look neater when its parked and also is practical. The holder is part number ZKC1550 according to the parts catalogue. The holder is made up of a spring, a backplate and a plastic molding.

Parts of the seatbelt holder including broken plastic part.

As you can imagine after 40 years the plastic is brittle and mine broken into 3 pieces. I have tried to repair it a few times with two component epoxy but these repairs were never successfully.

I thought maybe with 3D printing I could produce something to replace the plastic part.
