A lot of Volvo 740’s and 940’s are missing the button to turn on the hazard lights and need press on sharp plastic.
With this 3D drawing, a replacement button can be printed which has a tight fit and can therefore simply be pressed on it and then clamps. So no glue is needed.
On a hot day, the interior of a car can heat up to 70-80 degrees celcius. We therefore recommend printing this in at least PETG but even better ABS. These materials are well resistant to these higher temperatures.
