    During the last service my mechanic pointed out that a few of the rear lights were in danger of falling out. It turns out that this is a common problem. Many mechanics are rough when handling these holders and they probably get fragile with age too. I prefer to repair rather than replace. Luckily some kind soul has come up with a 3D printed solution seen here - https://grabcad.com/library/snap-in-ring-for-ferrari-testarossa-rear-bulb-holder-1

    I passed the file over to my local 3D print shop. Today I applied the repair. The repair part is a good tight fit but it may be easier to apply a little superglue to the edges to get it to stay in place.

    If anybody is experiencing the same problem but doesn't have access to a 3D print shop I may be able to help. Please message me privately.

    That's a great solution. I have glued mine before (silicone) and still had them come loose with the slightest bump. You are definitely correct, over time the heat in the engine bay causes these to get stuck and the tabs snap off easily. Several of us have resorted to removing the grill and lens to replace a bulb vs. risking snapping a connector. Replacement connectors or harness has never been available from the OEM (Carello) but an Fchat user (Verrel (sp?)) offers replacements he made from an original mold--but you still have to mangle the connector somewhat to install the replacement (as I recall, never tried). I will definitely have a few of those made, thanks for the tip!

    US$47 plus taxes and shipping is a premium price to pay for a bit of plastic. Good to have a choice of course....

    It would probably come close to that cost to have a 3d print shop replicate the part that you made. If you then factor in the value of your time dealing with the print shop and then repairing the socket, your costs are going to be higher than having and exact duplicate of the original part delivered to your door.

    I agree on some points - I am not pricing in my time. However, had I bought and fitted those Unobtanium branded parts I suspect that the total time spent will be not significantly different.

    3D printing is cheap for something so small. I paid about $13 for 3 but the costs drop as you print more because there is less admin overhead for the shop. Printing the complete holder would be a lot more. Dealing with a print shop was just a couple of email. Also, in the end, repairing the socket was easier than replacing it because the repair part slots straight in with no need to remove wires for the existing holder.

    All in all I believe that the fix is the superior solution in this particular case. This is not so in many other cases.

    Thank you very much for this solution
    I spent $20 (order minimum) for 8 of these slipons to fix 2 broken ones and they work like a charm.
    1) find a local 3D print shop and ask what’s the minimum (some had a minimum of $150)
    2) email the files in the zip, there’s two STL files but both look the same
    3) the same day you get them back and install in 2 mins with a bit of super glue.
    4) sockets fixed
    Thanks Adam
