SR Tachometer replica for Opel Kadett C

thingiverse

I wanted an OEM-looking tachometer and gauge set in my 1979 Opel Kadett C, but getting your hands on one is practically impossible, and expensive. So I made my own! I used the internals from an off-the-shelf 52 mm tachometer from my local auto parts store, Biltema. The part number is 32-224. The gauge needle is to small and complex to realistically print on an FDM printer, so I decided to use the needle off a broken speedometer I had laying around, it had to be drilled to accept the 1 mm shaft on the tachometer. I am working on a model of the needle though, I think it can be SLA printed without any issue. I had a local signmaker shop to print vinyl stickers for the gauge face. It turned out a bit too glossy to match the speedometer, but with matte laminating film on top it turned out close to perfect. I don't have any pictures with the matte film on yet. The face plate is 92mm diameter, but the sticker is sized for 85mm diameter.
