SR Tachometer replica for Opel Kadett C

thingiverse

I needed an OEM-looking tachometer and gauge set in my 1979 Opel Kadett C, but getting one's hands on it is nearly impossible and very expensive. So I made my own! I used the internals from a standard 52 mm tachometer from my local auto parts store, Biltema, with part number 32-224. The gauge needle is too small and intricate to print realistically on an FDM printer, so I decided to use the needle off a broken speedometer I had lying 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 issues. I took my gauge face to a local signmaker shop for vinyl sticker printing. It turned out a bit too shiny to match the speedometer, but with matte laminating film on top it turned out close to perfect. Unfortunately, I don't have any pictures yet with the matte film on. The face plate is 92mm in diameter, but the sticker is sized for 85mm diameter.
