    Hi All,
    I recently removed the shift gate on my 550 and encountered a disintegrated spacer/gasket. I did manage to order one from Ricambi, part #168955, but I didn't know if they would be able to get one at all so I had a friend draw up a CAD design for me just in case. I wanted to share it with everyone in case somebody would like to use it. The parts are identical for the 550/575, but not sure if they would properly fit a 456 or some others. For reference the general dimensions of the part is 103x76x12 in mm.

    Below are pics of the broken piece, the new part from Ricambi, and the CAD design links.

    Hope this gets some use!

    Forgot to mention, the file is an STL format ready for 3D printers.

    And here's a quick sketch of the dimensions.

    Brilliant - this is an ideal application for a 3d printer. Top work! :)

    My spacer is in pieces... 95 456. Any consensus if the 550 one will fit or has anyone tried to 3d print?

    Bolt hole spacing is the same. Worst case you would need to trim the edges. If you have a 3d printer or know someone that does, then the cost to make one is pennies. Might as well try?

    You'll need to open it in a slicer program (like Cura), or at least in a CAD program.

    Well this was a total success!

    The above file printed very nice and on my 456GT lined up perfectly, screw holes and all.

    If there was any critique, its that a very small portion is visible in the reverse notch. It doesn't interfere at all with operation. It was printed in a light color and i was worried it would be too easily seen, but really its not at all noticeable.

    I can make a small run of these available if there is any interest. Next version would likely be in a darker color or painted

    Awesome great to see it worked!
    Upon closer inspection now, looks like Ferrari changed the shift gate design between the 456 and 456M. Where the later model 98+ 456M uses the 550 shift gate. The earlier model 456 has a shift gate with a thinner left side wall. Since the design is based on the 550 that's why it's thicker than your gate.
    Interesting to see the cavallino design is also different.

    In any case you can just sand it down thinner so it looks better.

    I want to say I will trim that edge down or possibly just cut out that section, but unless it really drives me nuts or catches my eye, ill likely leave well enough alone for the time being

    Looking at the example above, I think the spacer can be seen in that one as well. Maybe that's just how Ferrari did it?

    Anyone else with an early model 456 chime in if their spacer is visible as well?

    Please tell me ABS, ASA, PETG, or another appropriate filament was used. If it was PLA, please reprint as PLA will deform/melt/sticky in summer cabin temperatures.

    PETG or ASA are easy to print and cost about the same as PLA and should work fine.

    As for the thickness differences on the 456 vs 456M, in your 3D printer slicer you can cut the bottom 6-10mm(?) off.

    For those without access to a 3D printer but need to get this area dialed in without the "real" part being available, here's an off-the-shelf option from Home Depot in the US to get workable spacing between the shifter and the gate: https://www.homedepot.com/p/Everbilt-1-2-in-Rubber-Flat-Washers-in-Black-10-Pack-865900/318764116

    They're stocked in-store and come in a 10-pack. They don't need to be stacked; just one in each corner gets you the space you need.

    These are 1/2" outer diameter, "00" rubber washers. I believe they're sold as faucet washers.

    I'm in a 456 GT, but I'd expect it to work for any cars with this shifter design.

    I didn't realize there isn't edit functionality here, and I should've just waited until I had the measurements before posting the abvove, but in case you can't get to a Home Depot, here are the full dimensions of a rubber washer that would work:

    00 rubber faucet washers ½" OD
    12.5mm outer diameter (0.500")
    4.6mm inner diameter (0.181")
    3.8mm thick (0.150")

    Ugh - burned by no edits again... it slipped my mind that my car had a custom-cut metal shim between the metal gate and what I think is called the "turret." So, it's not just the rubber washers that are needed, but something to make up the 4.1mm thickness of the metal shim my car arrived with. (picture attached).

    That said, I've since moved to a PETG 3D-printed replacement, and it takes care of all of this without needing the washers and has a more precise fit between the shifter rod, gate, and the foot on the rod that slides just below the gate when assembled.
