Recently replaced my Targa 27 with a Sealine F33 which is generally in very good nick but there are inevitably a couple of niggles; that's the nature of boats !

One of the light fittings in the guest cabin was not attached due to broken retainer clips/lugs (only 2 out of 8 left !). As these are completely internal, we don't need anything fancy to fix them.

Originally I thought about printing a complete ring that would sit inside the old rim but this would not have stressed the clips across the printer layers which isn't ideal. Eventually I decided that it would be best to make glue-in replacements that fitted the curvature of the inner ring:-

As they were a very snug fit I could use superglue to complete the job. Worked first time and popped in perfectly :)

I've attached the 3D files below in case they are useful to anyone else.
