    Hi,

    This thread to present the building steps of my DIY Huracan GT3 wheel replica.
    It has all the same buttons as the original, and is designed to fit my simplicity SW10C+ DDrive base presented here https://www.xsimulator.net/community/threads/simplicity-sw10c-direct-drive-early-review.12502/
    The only missing feature is the manual clutch, but I have a good one on my pedal set.

    000s.jpg

    It is based on the official wheel from Lambo website:
    000s official.jpg

    From this picture I made a drawing for correct dimensions (70mm adapter) and perimeters, and also verified that the buttons will fit behind the plate.
    (see the PDF for this drawing). the template is not exactly 280mm : you need to scale it up to match 280mm.

    then cutted a 6mm plexiglass with this template:
    001s.jpg

    After that, a little bit of sanding, drill holes for buttons, and cut/glue some foam using the plexiglass template:
    002s.jpg

    I use expansed foam sheets for isolation, they are about 8€/m2 for 30mm thickness.
    It is very easy to cut, sand and glue, and at the same time it is very resistant to compression.
    For sanding / finishing, just use #100 sand sheet.
    003s.jpg

    Then add carbon pattern sticker on the top of the plexiglass:
    004s.jpg

    Add buttons to check everything fits well.
    I threaded the holes in the plexiglass so that the buttons are screwed directly in the plexiglass and do not need nuts.
    005s.jpg

    The buttons I use are from aliexpress. I use them because they make a tactile 'click', and you are sure when you press them, even with gloves.

    The next step is to fit a suede leather on the foam.
    This is a quite delicate part of this build, but unfortunately I did not took any pictures of this.
    You just need patience to do it well. It took me about 2h30 to cover this wheel.
    I simply glued the leather on the foam. (do not use neoprene it does not stick to extruded foam)

    To get closer to the original:
    I 3D printed small rings around the buttons, and painted them mat black (made a special large one for the speed limiter)
    Added some stickers for the buttons (PDF for icons)
    006s.jpg
    (also 3D printed rotary buttons caps to match the original ones)

    The electronics part is based on USB Arduino pro micro (Sparkfun clone), and MMJoy firmware.
    Shifters are 3D printed. I made my own design since there is not much space to fit the Thingiverse ones.
    Electronics is placed between the wheel and the quick release adapter, on a dedicated 3D printed holder.
    I did not took the time to print an enclosure for everything, this will be the next and final step.

    if you need stl files, just contact me. (I might push them on thingiverse one day...)

    Hope you enjoyed, feel free to comment !!!

    Pretty awesome, thanks! Just wondering, what type of foam is that? Can it be found on ebay?

    Looks good, but is the plexiglass going to handle the strain.
    If it was polycarbonate I would say yes.

    When translated it says Extruded Polystyrene XPS, so I'm guessing this is about the same thing? https://nettbutikk.byggern.no/byggevarer-og-trelast/isolasjon-og-byggfolie/ekstrudert-polystyren-xps/jackofoam-200-isolasjon-50mm-x
    IIRC 6 mm plexiglass will be quite stiff, so I think it should hold up quite fine.

    Yes, nicely done and all with pretty inexpensive materials. The finished wheel looks great. Cheers M8.

    Could you please share the stl for the shifters and the rest? It looks so cool!

    Great Job.

    If possible can you scan the base of your wheel. I can make a dxf file and a stl file for those who wants to build this like yours. With the dxf file it could be possible to cnc 4 mm alloy easily.
