When I replaced my Targa 27 with a Sealine F33 there were 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:-
I printed half a dozen but only needed to use two :-
As they were a very snug fit I could use superglue to complete the job. Worked first time and popped in perfectly :)
